Hi,
I created Lora project which send and receive data. I designed my board, no TCXO.
My schematic:
My result:
the random value is 0, TxTimeout everytime.
I replaced to new MCU, new RF switch IC but result not change. Please support me.
Thanks.

Did you drop the bandwidth or increase the message size?
Interrupts working?
Clock or Timers ticking?
Perhaps look at how it seeds random

I have the other board the random value is not 0 but the LoRa Tx status is always TxTimeout.

I follow the Ping Pong example project. I soldered the R12 resistor to choose LP LoRa communication, my project work correctly but I soldered the R13 resistor to choose HP LoRa communication, the LoRa Tx status is always TxTimeout
Please support me.
Thank you very much
