TTGO T3 V2.1_1.6.1 blank screen

Hi, I have TTGO T3 V2.1_1.6.1 868mhz module and I’ve uploaded ttgo-lora32-v1-868mhz config via web. It seems that V1 config is not fully compatible with V2 board. Device is working, I can configure it but OLED sceen is not working and it is blank. What could be the problem?

Hi,

You would need to make your own configuration for the v2 lora, by taking inspiration from the lilygo rtl 433 ones and replace the rtl 433 related settings by the LORA ones.
