VictronConnect 6.12 detects the product name correctly, but it seems to be trying to upload Bluetooth firmware V2.52 for a VE.Direct Smart Dongle (?) to the MPPT 100/20 and gets stuck at 84% before failing every time. Now the earlier BT firmware is gone.
Background info: I had to reset the network settings on the phone to delete all BT configuration, reset the MPPT PIN using the PUK, re-pair the devices, connect and set a new PIN. This was prompted by an impossibility to connect, failing at 20% no matter what I tried. I was then prompted to update the BT firmware by the latest app and it broke the BT interface.
Now I can’t really see a way out without an updated release of the app.
It was still paired. I tried not to lose this as it can be so problematic to restore these days. I recovered the device using another phone, then I had the same problem with the charger firmware update, also needed to use another phone to recover that.
Now I am back to square one, connection fails at 20%, PIN reset fails too and I can’t connect at all, but the device is up-to-date and functional. I reset all the network settings on the phone, cleared cache and storage for the app, rebooted the phone and I still can’t connect any more or reset the PIN… It seems to have something to do with the fact that another device was paired with the SmartSolar. Next step might be using another phone again to do a PIN reset and then try again.
I have both a 75/15 and a 100/20 and I have had exactly the same issues with both. Honestly, it has been a nightmare since V6.00 came in contact with the devices. It always worked fine until then. Now it looks like I need another phone and I really wish I could do these things from Windows instead.
I uninstalled V6.12, installed V5.106, same situation: can’t get past 20% connect, can’t reset the PIN (the device doesn’t respond with all 3 LEDs flashing) and it fails.
I re-upgraded to V6.12 and suddenly I was able to reset the PIN. Now I can attempt to connect, it gets to 80% and asks for the PIN for pairing, but entering it (“000000”) causes a loop, the connection attempt restarts from 0% and ask for the PIN again. Same behaviour as described here: Victron Connect Pairing Issue (Android 15)
If I try to pair directly from Android, the 3 LEDs flash together 5-8 times on the device and stop. It is not long enough to enter the PIN and pairing fails too.
Can you try to reset the PIN again and then immediately try to connect using the PIN “000000”? When this fails, please create a service report directly after this and post that here. The procedure to create a service report can be found here: 13. Troubleshooting
Unfortunately, there is not much that can be seen in the service report. I see that it waits for a successful bonding, but it seems to just fail when the pincode is given.
I also see that you are running a really old phone (Galaxy S4) with (a non official) Android 12L. Where did you get the ROM?
What you could try is download the nRF Connect application from Nordic Semiconductors and use that to connect and bond to the SmartSolar. If it is an issue with our app, then this should work. If it is an issue with the Android release, then there is not much that we can do.
