Help with Telemetry on QWIIC Module

[haroldboom]

Hi all,
I tried to get help a couple of times on the MeshCore discord in troubleshooting but i didnt get any responses.

I have a MPPT solar battery charger and regulator for my Rak Wisblock (https://www.etsy.com/au/listing/1609406536/mppt-solar-battery-charger-for-iot?show_sold_out_detail=1). I recently moved to Meshcore and I was wondering if I can get the telemetry from it like I did on Meshtastic? It’s connected via a qwiic module and it’s at address 66. The command I ran in Meshtastic was “meshtastic --set power.device_battery_ina_address 66” and the data would appear on telemetry channel 2 and 3

Thanks!

I appears the chip is supported https://github.com/meshcore-dev/MeshCore/blob/e812632235274ffd2382adf5354168aec765d416/src/helpers/sensors/EnvironmentSensorManager.cpp#L64C5-L64C24

I believe you need to build the firmware with ENV_INCLUDE_INA3221 set for the variant in it's platformio.ini, but I may be wrong. I also think the address is different so you might have to override the address build variable as well.

Thanks mate, hopefully someone has done this before and can let me know exactly what I need to change. The node is inaccessible so I can’t afford to brick it

I decided to just pull the node out and reflash it.

I tried the following but it didnt work, when I open Telemetry on the MeshCore app it doesn't show any new data. I also tried just -D ENV_INCLUDE_INA3221=1 without -D TELEM_INA3221_ADDRESS=0x42 but no dice;

What about with TELEM_INA3221_ADDRESS=0x66 as thats the address right?

Hey mate, its in hex so 0x42 is 66 but I worked out the issue. The GPS is booting up on 0x42 so that's why it wasn't working. I managed to get the GPS to move to 0x55 but then the data coming through was all 0 on all channels from the INA3221 and nothing I tried would give me any data on.

💀 haha ya that makes sense.. sorry

Hopefully someone else has ideas on moving forward.

Nar all good mate, thanks for your help. Fingers crossed someone has the answer!
