I have been using Heltec WiFi LoRa 32 V2 boards for some time, with a sketch using LoRa, OLED and BLE, everything working fine.
The last boards we have bought are V3, so I migrated everything to the new version (board, libraries,…). I managed to make everything work in both board versions, but the power consumption is high in the V3 board and it gets hot, even if everything works fine (the heat seems to come from the area of the microcontroller).
I have narrowed the problem to the bluetooth, as the same happens using the “BLE_uart example” provided with the 0.0.7 board libraries. I have tried the example sketch with 3 different V3 boards and the same happens. But not in V2 boards.
Does anyone know anything about this?
