Hi,

I created Lora project which send and receive data. I designed my board, no TCXO.

My schematic:

0693W00000UFQ6yQAH.pngMy result:

0693W00000UFQ2IQAX.pngthe 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?

I​nterrupts working?

Clock or Timers ticking?

P​erhaps 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
