Hi everybody,
I’m comming to you because I have an issue on my project:
https://www.thethingsnetwork.org/forum/t/connected-hive/33430
I’m using a Dragino Hat v1.0 on my raspberry pi, configured as a single channel “gateway”, and a PCB I made with an ESP32 and RFM95 lora module on it. Since 4 months I put it in test to check if all is working fine, For maybe a month the data I receive has not been arriving every time. I use my ESP in Deep sleep mode every 2 hours. By looking more closely and by changing my deep sleep to 1 min I saw in the traffic gateway that my device address change many time. The good address is normaly 26 01 10 A9
I don’t undersant what is going one…
My code may be help:
