Bluetooth Image


Cerbo GX bluetooth connection lost.

Hi all,

I accidentally hit "forget this device" for the bluetooth connection to my Cerbo GX and from that point i am not able to find Cerbo GX in my bluetooth list on an iphone running the latest OS version.

I tried restarting both Cerbo and the iphone with no luck. I also tried to change the Cerbo GX name but again this failed although i am able to connect to it using bleutooth using another phone or any other bleutooth device (i.e. my laptop).

It seems that resetting my network settings on the iphone will fix this issue but it will also delete all my wi-fi settings which i want to avoid.

Anyone had this issue before?

Thank you in advance.

Cerbo GX denying WiFi/Bluetooth and Remote Console, i tried all i could find here in the Forum, what else might help?

Hey People,

i got my Cerbo like 2 Weeks ago and almost everything worked fine in the very beginning. But only for a very short time. When i first connctec via BT via Victron Connect App it worked, same with WiFi. But after Firmware Update 2.63 it stoped both connecting with WiFi and Bluetooth. I also discovered that i don't have access to Remote Console. I rebooted, i reinstalled older Firmware, i disconnected the Cerbo Touch Display, i moved it a bit more far away of al the other Victron Parts. Nothing helped.

But one thing is interesting. I already connected with 4 different WiFi Networks and all of them worked for a very short period. Yesterday i had an idea and tried to connect to my neighbors Network and it worked for a few minutes, but unfortunately then lost connection ever since. No reconnection possible.

The Cerbo is showing correctly all Networks and it seams the new networks might work in the very beginning.

Another thing i discovered, once i tried connecting the Cerbo with its own Network, the Venus HQXXX... it did. After that i had very short connection with my main WiFi Network again - but now even the Venus HQ Network doesn't connect any more. Saying Failure/Disconnected.

Now i´m really out of ideas what might help. Hopefully i described everything in the best way so you could understand what my issue is. Thanks for help. Cheers, Marcel

Questions about monitoring mostly Victron system

I was hoping to go all-Victron for my van build, but it is beginning to look like I cannot go all-Victron. (See my other question, "Does the MultiPlus 3 kVA Inverter/Charger allow me to set an upper limit on the wattage?")

Here's my current thinking:

  • 1x Lithionics GTX12V315A Battery
  • 2x-3x Victron Orion Smart DC-DC Charger - 30A
  • Victron Solar MPPT 100/50
  • Xantrex XC Pro 3000 inverter/charger

1) Assuming I go all Victron, except for inverter/charger, what are my monitoring choices?

2) For example, should I still consider Cerbo GX?

3) If I do go with Cerbo, do I actually need the GX Touch 50 to start with, or can I just use my iPhone to start with, and add the Touch later if I decide it would be useful?

4) On the MPPT, there is Smart and there is Blue. Does getting one versus the other have an impact on monitoring? If so, what?(All of these units will be in close proximity to each other, except for possibly the Touch, in case that matters.)

5) If I go with the Xantrex, I will get their Control Panel. Given that, is there any reason to consider a Victron Smart Shunt? (I am admittedly not entirely sure exactly how and when one would use the Smart Shunt, hence the vague question :-)

For the record, I am brand new to this rodeo, so I am likely to have missed some very basic info. Feel free to correct me and/or redirect me.

Upgraded batteries and iphone now can't pair

Just upgraded our RV batteries from AGM to lithium and a new iphone 12 pro. Went to the Victron App to change the settings. I can see the Victron Controller (mppt 75/15)but when I select it, it asks for my pin. I haven't changed it, still six 000000, but the pin isn't accepted and after three or four attempts it just refers me to the owner's manual. I have deleted the app and reinstalled it. Each time when I open it, it recognizes my controller but won't pair.

Cerbo GX wifi issues

I have had my Cerbo GX with touchscreen installed in my motorhome for a couple months now. Most of the time it won't stay connected to my WiFi, which is about 8 ft above it. I use a Pepwave Max Transit Duo WiFi modem, so it's a pretty strong unit and the Cerbo shows around 75-80% signal strength. I can force it to connect, and sometimes it stays connected, sometimes it doesn't. Even when it's connected, I can't connect to the remote console much of the time. I'm on Firmware 2.57. Any suggestions?

Lost my bluetooth on my SmartSolar MPPT 150/70

I have a Victron BMV 712 and a Smartsolar MPPT 15/70. Both were appearing on my Victron Connect. Now only my BMV is appearing. I have tried turning bluetooth on and off, I have uninstalled and reinstalled the app. The green light is on the MPPT itself.

What is your recommendation?

Security Issue / Password / Bluetooth / SmartSolar MPPT 100/20

Hello everybody,

I was somehow surprised as a friend of mine demonstrated to login into my SmartSolar with the default pin 000000 - I directly changed the password (which was not set to default) to a new password - but still he was able to login.

The app on ios confirms the password change - it even confirms that the old password / pin is not set to default.

Firmware SmartSolar MPPT 100/20 is v1.39
Firmware VictronConnect on IOS is v5.7

Any hint or idea is welcome

Smart shunt Bluetooth light flashing but not appearing in app

I have a smart shunt fitted to my aux battery and all was well until about a week ago it stopped appearing in the app and will no longer connect.

I suspected that a lot of wet weather recently may have been to blame. I sprayed WD-40 inside the unit to disperse any potential moisture.

However during the whole time I have not been able to connect, the Bluetooth light has been flashing as normal. Perhaps it's another issue?

Could anyone help point me in the right direction troubleshooting the issue?

Poor bluetooth connectivity with Orion-Tr Smart


I've just installed an Orion-Tr Smart DC-DC charger to my camper van. It's installed under the bonnet along with my Victon SmartShunt and SmartSolar MPPT controller.

I can connect to the SmartShunt and MPPT from up to 2 metres away and inside the vehicle no problem. However, the Orion-Tr will only connect if my phone is literally about 20cm away from the device and even then it's unreliable. It will not connect from inside the vehicle at all.

Is there something wrong with my Orion-Tr? It's very disappointing that a premium product from a well respected company has this problem. Also a little disappointed that it does not support VE networking.

Hopefully there is a solution?

Orion-Tr Smart 24/12-30A - poor bluetooth perfomance

Hi all,

I have installed an Orion Tr Smart 24/12 30A in my motorhome. I took the choice for this model because I want to be able to switch it on/off while driving.

But the bluetooth performance is very poor. The device is in mounted in the garage of my motorhome. During the instalation in the garage I checked receiving my MPPT and BMV (mounted inside the motorhome) there without any problems. Now the situation is as follow:

Inside the motorhome I can reach my MPPT and BMV but not the Orion in the garage. I try to reach it inside only a few cm away at the other side of the compound wall with no result.

Inside my garage I can receive all 3 devices.

Beside the motorhome I can receive the MPPT and BMV without problems, the Orion only at the door of my garage if it is open.

Is there any option to a better performance ? I know the option to use a cable to switch the device but I bought this device to to it by bluetooth.

Battery Protect and BMV712 Bluetooth pairing-PUK code

My battery protect, & BMV712, unpaired themselves with the recent app update and suddenly are in need of a ”code displayed on.....“ whatever. These and the charge controller have been installed and trouble free for over a year. Research told me that I need a PUK code on the device which is alphanumeric. The data entry on the iPhone app is numaric only. I removed the bluetooth from my iPhone, disconnected the batteries for a short while, etc. no help. Same issue. 000000 didn’t work either. The solar charger pairs just by pressing continue w/o entering anything, but then it has power removed when the Airstream is in storage. The battery protect is difficult to access (which is why we bought the Bluetooth!) What is a guy supposed do do?

Why is disabling the Lithium Smart batteries Bluetooth Connection permanent?

Catching up on reading and come across this in Help for Victron Connect. Anyone know why it is irreversible?

Lithium Smart batteries

The product page can be found here.
Once Bluetooth is disabled, it is disabled permanently and is irreversible. This means that VictronConnect will ask for a confirmation code displayed in the dialogue; if you are sure that you want to permanently disable Bluetooth, enter the code displayed and choose “Ok”.

Bluetooth connection impossible

I own a SmartSolar 75/15 without any issues so far, with the device or with the Victron Connect App.

Lately, I can't connect my phone (or another phone, both Android) to the App. The device appears on the list, but when I click on the device, the progress bar goes to 20%, then back to 1%, and so on until the message "unable to connect blabla" appears.

I've also tried to reset the PIN with the PUK code, and still an errors shows saying unable to reset the PIN number.

On top of that, the device seems to work correctly as the bulk blue led is steady while the panels are at sun.

I've of course installed/uninstalled/cleared cache of the app several times, and the latest version was used.

Thanks for your time,

Victron connect android app add classic Bluetooth scan feature

Hi everyone!,

This is my first post and my first question, I recently bought Victron Bluesolar MPPT 75/15, and I made a custom usb cable using Usb to UART module and I could connect my controller to the victron connect software on windows and the victron connect app on Android, but I wanted to connect wirelessly with Bluetooth, so I have used HC - 05 Bluetooth module and connected it directly to the victron bluesolar Mppt to the communication port.

By doing this, I was able to access and change the configuration of the Mppt controller via Bluetooth from victron connect software in windows, but I also want to access my controller via Android app instead of turning on the computer every time.

So I request to please add the classic Bluetooth scan functionality in the victron connect android app, as currently the android app only searches for Bluetooth low energy devices. But the HC-05 Bluetooth module is not Bluetooth low energy, and it's Bluetooth version is 2.0.

MPPT 75 15 issue


I am having a problem with my MPPT 75 15. I recently had a problem with my old solar panels and had to replace them (they were not secured properly on to vehicle by installer and ripped off, a long story!)

When I plug my battery wires my charge controller, the blue flashing light immediately comes on. No green light.

When I plug in my PV cables, i get zero voltage and the blue light still blinks. My PV cables, before plugging into the controller, get 23V from my panels. It's not until I attach them that I get zero volts.

I checked the fuse and it is fine, but the PIN bridge is missing. Is that an issue?

Is my charge controller fried? Or is there an obvious solution?

SmartShunt placement for best Bluetooth connectivity

I'm about to purchase a SmartShunt -- love the concept!. I see in this forum there are some folks experiencing Bluetooth connectivity issues. As with any radio, it can be interfered with by EMI and metal structure obstruction. I plan to use the SmartShunt in my 5th wheel. The front compartment has the batteries, charge controllers, etc. and all electrical wiring. I suspect quite a bit of EMI in this compartment. Since all current goes through the negative side of the shunt, near-to-battery placement makes sense to reduce current loss... in other words, the Bluetooth transmitter is located next to the worst EMI.

Where is the best placement for the SmartShunt?

Why can't Victron Connect see my charger?

I've just bought a Victron Energy Blue Smart IP 65 charger for my leisure battery. As a charger it seems to be fine, but I can't get a Bluetooth connection to my phone.

I've installed the Android Victron Connect App from the Google Play Store and granted it the permissions which it wanted (Location and Storage). However, when I fire it up it says it can't see the charger. The list of devices to which it offers to connect is empty. This is despite the fact that if I do a Bluetooth browse from the OS Bluetooth page it can see the charger just fine (and indeed, pair with it).

I've tried restarting both charger and phone but the problem persists. I tried using an older phone and it worked on that, but I don't want to have to carry a separate phone just to use this one app.

Although I can see the charger from the OS pairing dialogue, and successfully pair with it, the app still won't talk to it. I then do a "forget" from the OS before going back to trying to establish a pairing within the app.

My phone is a Moto G7 Power, running Android 9.

Attached is a service report from the app.


As a suggestion - and in the light of the multiple complaints from other users about the app requiring unnecessary permissions - it would make sense to stop trying to do the pairing from within the app. Let the OS dialogue handle the pairing in the way that's intended, then just use the device once it's been paired.

Does the Orion Smart DC-DC charger maintain the last configuration set with Bluetooth when all power removed then reconnected?

I am going to install an Orion-TR 12-12 30amp isolated charger with Bluetooth on a MB Sprinter RV. If the vehicle is parked for more than 2 weeks, the vehicle’s owner’s manual tells you to disconnect the vehicle’s battery ground wire. My question is: Does the charger maintain the last setting set with Bluetooth or does it go to some default setting when all power is removed then reconnected? I have LiFePo batteries, so this is a concern.
