ESP32 LoRa TX/RX missing chars, after changing board

[maxbundscherer]

Hello all,

maybe someone of you knows further: I have developed a software for a Heltec WiFi LoRA 32 (V2) OLED board. For this I used Arduino IDE (with external editor) and the official Heltec Board-Manger URL and the board WiFi LoRA 32 (V2). Everything works fine.

Now I want to adapt the software to other boards, for example to LilyGo TTGO. For this I used the espressif ESP 32 board manger URL and the Heltec WiFi LoRa 32(V2) board (to have the possibility to change to other boards later). When I use the same Heltec boards, some characters are missing when sending and receiving LoRa and I don't understand why. I only changed the board (with board manager URL) in the Arduino IDE. Everything else is working fine.

I have another problem with the Heltec boards: The LoRa transmission breaks completely after a random time when I send packets from a background task. From then on, all transmissions become erroneous until the board is restarted. The signal doesn't look reasonable even over SDR. The transmissions themselves also take almost no time at all.

Hopefully one of you knows more, I've spent a lot of time troubleshooting now. I have yet to specify the exact board URLs on the https://github.com/maxbundscherer/indep ... veloper.md page and I have specified the hardware on https://github.com/maxbundscherer/indep ... ardware.md.
