This update will not be reported by the App for now as it is a minor code optimization update, no changes for users.

Re: New MySondy GO Firmware 3.10

Dear Mirko,
I am using firmware version v3.1 with this hardware: LILYGO TTGO Meshtastic T-Beam V1.2 ESP32 LoRa Development Board 433MHz with AXP2101 power management IC. https://www.aliexpress.com/item/4001178678568.html
Unfortunately, neither the iOS MySondy GO 3.0 application nor the device's display shows the battery voltage, it always shows the maximum value (even when the battery is discharged). I don't know exactly how the battery voltage measurement is implemented, is an ADC used or is it done on the I2C bus of the power management integrated circuit... Is there any hardware/software solution to this problem?
Thank you in advance for your help.
