CerboGX v2.86 Bluetooth Issues

Updated from v2.84 today to v2.86 and lost all Ruuvi sensors. Rolling back doesn't restore them. Cannot add new Ruuvi sensors either as they are not "seen" by the Cerbo.

It seems that bluetooth not working on this version, and slightly worrying that rolling back doesn't fix the problem. I notice multiple other posts from users reporting similar issues when updating.

If there is not an update planned to fix this soon could someone explain what I need to do to reset the bluetooth adaptor (perhaps using command line)? Thanks

Report this in the modifications section on the V2.86 topic.

Hi @Miles Carter,

Are you using the built in bluetooth, or an external USB bluetooth dongle?

The built in bluetooth is not supported for Ruuvi sensors as it is disabled due to temperature - so is only suitable for the initial commission setting the networking configuration - there is more detail in the Cerbo GX manual here - https://www.victronenergy.com/media/pg/Cerbo_GX/en/installation.html#UUID-4d5df29c-761e-cfcc-9e2c-8230f126e7bb_section-idm4637103287267232851365842652

Hi Guy, thanks for your answer. I think there is a bigger issue here than you describe as after the firmware update the bluetooth light on the Cerbo GX is permanently "off" even though the bluetooth is turned "on" in the software (see attached photo). I also cannot "see" the Cerbo using the bluetooth connection on my phone.


Yes, I was using Ruuvi tags before the firmware update and they all worked perfectly until I did the update. The tags are located within 2-3 metres of the Cerbo GX and there was never a connection issue before the update. I do accept your comment, however, that the bluetooth in the Cerbo is not designed for Ruuvi tags.

I did eventually manage to resolve this by rebooting the Cerbo GX about 5 times, and on the 5th attempt the bluetooth light came on again and I can now connect to it via Bluetooth and the Ruuvi tags work again. What was worrying was that it took 5 reboots AFTER rolling back the firmware to 2.84 to get it working.

Whilst I love the regular firmware updates, I think there's a real risk of Victron having a lot of in-warranty Cerbo GX claim requests if firmware is released that causes major issues like this that are not acknowledged. Reading through the forums it is clear that many other users have experienced exactly the same issue that I have, and almost all of the answers state the user should buy a bluetooth dongle to resolve the problem. This cannot be correct as the firmware update caused the bluetooth to shutdown completely for all devices (at least this is what happened in my case).

My Ruuvi sensors worked fine on the internal Bluetooth. However, once I got past about 10 sensors, including bluetooth water and gas tank sensors, then I started to see a few sensors drop in and out of connection. had to start using an external bluetooth adaptor.
