Hello everyone, I have copied this project, but I can't transmit or receive. What could be the problem? Thank you!!!

Error -2 means that RADIOLIB_ERR_CHIP_NOT_FOUND, soldering issue, wrong pinouts or wrong module.

Thank you for your answer. I will continue to investigate the issue。

The transmitter module cannot be turned on without an antenna, it may be damaged, or in the best case the output transistor will burn out...
After soldering the module, clean the contacts with post-soldering alcohol, and between the module contacts as well

1. I checked soldering and pinouts---no probram founded
2. I tried the example of radiolib :"SX126x_Transmit_Blocking" and "SX126x_Receive_Blocking" ----worked well
3. change envs to esp32dev_e22_sx1262 and changed the CFG_LORA_FREQ_RX CFG_LORA_FREQ_TX---now it woked,but voice delay time up to about 2seconds,Is there any problem with this？

thanks
