@KevinKW87 Could you please confirm if this is a case of the battery not reporting it's % (check the screen), or is it that the data passed over mqtt is malformed (as it is above).

[KevinKW87]

Its that the battery isn't reporting its %, I did the malforming to highlight the batteryLevel.

In the 11200 Spec there's this definition : #define PIN_VBAT WB_A0 (WB_A0 being 36) - The actual voltage divider of the baseboard is connected to AIN0 so that seems correct.

Good catch. I also need to audit the SX1262 pin setup on this board, as I measured very low output on my TinySA compared to the RAK-4631 and even an SX1272 T-Beam.

Closing as 1.2 is not getting any updates, please re-test on 1.3 and re-open if it is still an issue.
