5G (GSM module) for VenusOS


I'm currently running an RPi 4b with Venus OS 2.93. Currently I'm using the SIM7600G Hat together with a Telekom Sim Card very well via LTE/4G. Because of the Telekom contract also includes 5G, I wondered if there is already some support for 5G in Venus OS?

There is already a SIM8200 hat for RPi, which supports 5G, even though it's quite expensive :-)

I thought about just buying it and give it a try, but I could imagine, that there has to be some updates of the 5G AT-commands.

Is there already something available or if not something in develop?

Thank you!

GSM - SIM imei

Hello everyone,

I had to change the sim card I used for my GX LTE device and now I can't seem to change the IMEI number which means no way of reading the sim card...
Any advice?
I thought about resetting the GX LTE device but I have no clue on how to do it...

System is connected to a Cerbo.

Many thanks,

Remote start Easy Solar

Hi! I have an Easy Solar which i controlled by a CCGX. This is on a cabin with off grid system. When I`m not at my cabin, I usually switch off the Easy Solar to save my battery capasity. My question is, which opportunities do I have switching on my Easy Solar from remote? I have a GSM relay I can activate with my cell phone, can I use this signal to remote start the Easy Solar via the CCGX? Bare in mind that I don`t have any internet connection before my Easy Solar is active/switched on.

GSM modem goes offline


I have an issue similiar to GSM modem offline 3.

We are running 8 off-grid systems (Multiplus + Cerbo GX) in Malawi, with more coming. Comms is through the Victron 4G GSM dongle using Airtel (mostly) or TNM sims. On commissioning, all systems were online. However, during the first couple of days, five systems dropped (and remained) offline while three have remained online.

The "worst" example dropped offline 12 days ago, never to reappear. None of the systems that have been more than a few minutes offline have recovered. At the same time, we have other GSM based equipment onsite that has remained online. Some sites are clearly far off grid, but weak signal locations have extra antennas. Connection drop does not seem to only his weak connection sites. It takes between an hour and a day to reach these sites from the capital, hence we need to go prepared.

We have been to the first (closest) site to assess. Site has good Airtel coverage, but we first tried TNM, and the GSM/Cerbo produced error 153 (Routing error). With an Airtel sim it complained about APN for a few minutes before going online with good reception. (3 bars), allowing remote VRM login. After leaving the site, the connection dropped within an hour, never to recover.

Relevant settings:

- Cerbo GX Firmware version v2.70~5-large-18

- APN: set to “Use Default”. Required APN is “internet” for both Malawi carriers. Since we had access, I do not consider this the root cause, but we are happy to change this. We have set this to "internet" for one of the working connections, this works too.

- Settings->VRM-> «Reboot device on no contact with VRM» was not enabled at first. We have instructed that new installations should enable this feature. However, this is in my opinion a way around the problem rather than a real repair.

- FW update set to "Check only" to avoid uncontrolled updates and data use.

- Roaming is off. Will enabling this give us greater chances of remaining online?

Is there anything Victron or us can do here? Could there be a specific airtel/TNM Malawi<-->Victron issue that prevents the cerbo to reconnect if connection drops? Any advice would be good before we start driving around the country.

I have a rather large Victron System that was recently commissioned and all was great. We added a GSM 4G-LTE and everything went haywire in regards to the MFD Integration. If the GSM is unplugged the APP on the SIMRAD MFD works great. And if the SIMRAD is unplugged the GSM works great and will work as intended. WIth Both plugged into the CERBO the APP stops working on the MFD and we lose INTERNET DATA and connection to the VRM. Sometimes the MFD will pop up a screen saying to "Make sure MQTT Plaintext is on", which it is. I have a feeling this has to do with SIMRADS DHCP server in their system and addressing conflicts, but I am not sure. Have you ever had this issue before? What can I do to remedy this?

Using the GX LTE 4G as failover.


Just bought a GX LTE 4G modem and have connected it to my CCGX. The CCGX is already connected to my LAN which has a router connected to the Internet. The router however needs 230V which it gets from my Inverter. The plan is to use the LTE modem to power the inverter on and off to save power in the winter.

The LTE modem is working fine, but I have to reboot the CCGX to make it switch between the LAN router and the modem. So if the CCGX uses the router and I shut down the inverter I loose connection because the CCGX needs a reboot to switch to the modem.

The manual states that there is a failover between the modem and WiFi, but not between modem and LAN..

Any bright ideas out there? :)

Cerbo GX FW 2.60 and GX 4G Connection Issue

Hi All,

I installed a GX LTE 4G today and found that an icon was trying to display on the top right by the clock, and that the system was reporting internet Offline, when the system was clearly online and communicating with VRM. See screen shots

I also logged in via ssh and found that the ppp0 interface had received an IP address and was able to do DNS lookups and ping.

I wasn't able to do any further investigation. Since I have got home what I have noticed is that the location symbol moves one to the right and back again.
