Fix your configuration, fake gps coordinates should not be at 0,0.

Also add some information to your message, don’t expect us to guess what is and what isn’t happening. Good starting point would be to answer the next questions:

  • What frequency plan are you using?
  • What is your hardware?
  • Where in the world are you located?
  • Why do you expect to receive data? (Is there a known working node sending packets?)

And finally, learn to format your postings properly.

Thank you for your reply.

  1. I am using Europe868MHz frequency plan.
  2. My gateway is based on the iC880a USB concentrator with a Raspberry Pi host.
  3. My location is Tunis,Tunisia.
  4. I am using STMicroelectronics STM32 LoRa (B-L072Z-LRWAN1) to send packets to the getaway,I tried to run the end node project exemple.

I tried to debug while sending the packets :

APP_VERSION= 01.03.00.00
MAC_VERSION= 04.04.02.00
ABP

DevEui= 00-2E-D3-55-F7-29-55-73

DevAdd= 260115BB

NwkSKey= 6A AA A2 CF 5F 70 84 DB 30 E7 31 E8 E4 25 35 B6

AppSKey= 3F 03 61 F0 1A 5D 73 C1 24 BD C6 49 D6 36 B8 8A
