TLora32 2.1 does not send batteryLevel to mesh

jaykayenn commented 2 years ago

Remote nodes running on TLora32 2.1 always appear in nodelist with no batteryLevel.

Setup a network of Meshtastic nodes connected to a channel
View list of nodes via CLI or phone app
See that any remote nodes running on TLora do not have batteryLevel in the Nodeinfo
TLora nodes will show their own batteryLevel when viewing node list locally, but will not see batteryLevel of other TLora.
TBeams do not have this issue. TLora will see remote TBeam batteryLevels.

the board says t3_v1.6.1, the purchase link says v2.1 1.6.1 and the schematic says t3 v1.6.1

board was purchased from our supported page

Note to self: confirm our algorithm confirms the following observation

battery voltage: 4v voltage at battery pin: 1.865

Take your measurement at IO35 So, that's one voltage measurement at io35 and another at the battery jkn — Today at 11:35 PM 4v -- 1.865v

The T3 V1.6 is the V2.1 1.6. I know, it's confusing right?

TTGO LoRa32 V2.1.6 (aka T3 V1.6, aka LoRa32 V2.1 release 1.6): Is labeled T3 V1.6, 20180506 on the PCB. Similar to V2.1.5 with changes and improvements: Changes in pins / GPIOs. Uses GPIO23 for LoRa RST. Uses GPIO25 for onboard LED. Uses GPIO35 as ADC for battery voltage measurement (uses 100k/100k divider).

This thread has a pretty comprehensive summary of the TLoRA / LoRA32 board variants. https://www.thethingsnetwork.org/forum/t/big-esp32-sx127x-topic-part-3/18436 I think there may be some more recent revisions available that aren't covered, especially given the fact that Lilygo has made small changes to the T-Beam such as swapping out usb serial ICs.

This issue has been mentioned on Meshtastic. There might be relevant details there:

That thread was made in error, and is now talking about something else unfortunately.

Tested that batteryLevel is sent in position packets to the mesh as expected 1.2.53. May be an issue in the python api if the display is wrong.
