Hi Bernd, I hope you're fine. I try send "Helllo" over LoRaWAN wşth ESP32. But I saw serial "timeout waiting for BUSY now". I defined txen and rxen. And I send picture and LoraWAN settings. What should i change, this is the first time i saw such an error. ADR : Disabled Datarate : DR_2 Duty cycles : Enabled Region : LORAMAC_REGION_EU868 LORAWAN_APP_INTERVAL 20000 LMH_UNCONFIRMED_MSG;

@Muuhoooo You closed it, so I guess you solved it.

Timeout waiting for busy is caused by the SPI communication not working or Busy pin of SX1262 not connected or defined incorrect.

Muuhoooo commented 2 years ago

Hi Bernd, I saw another issue and I tried but did not solved. I checked the spi and all the other pins connected to the sx1262 with a multimeter.All of them are all connected and defined in my code. Again, an interesting error could not make sense.

I tried new SX1262 and ESP32 and I checked all pins and same result. "Timeout Waiting For BUSY now"

beegee-tokyo commented 2 years ago

Can you retry your LoRa P2P test that you mentioned earlier.

I have an ESP32 working with an SX1262 (not eByte) without problems using LoRaWAN and sending packets. It's up since weeks. And another ESP32 connected to the same eByte module working on LoRa P2P working since months.

I just cannot take them out for tests, because they are part of my home control system.

So I am not sure how to solve your problem, but I am quite sure it is not the library.

Muuhoooo commented 2 years ago

Okey understand. Thank you very much for your help.

Muuhoooo commented 2 years ago

And LoRa P2P test is successful. I have seen serial screen "Hello World".

Digged in my "old devices cabinet" and found my Adafruit ESP32 Feather and the Alora1262 Feather (which has the eByte module on it):
