Issue: I have 5 sets of RAK4200-based devices. Rak4200 modules are connected to the chirpstack gateway running on the RAK5146 concentrator. All are Running on the AU915 region. After a few days of setting up the devices, it gives the error 96 and 94 as well on RAK4200 modules. But some modules are still working with the same configuration simultaneously. I have tried with the RAK serial port tool as well.
Setup: Rak4200 devices are connected to the serial port of the Atmega32u4 chip. the microcontroller is sending the packets every 10 seconds. Rak4200 is running on SF12 configuration. also, these devices are not very far away (about 20 meters apart). Gateway is connected to RAK 8dBi Fiberglass Antenna. and RAK4200 modules have 902-930 Mhz Rak 2dBi SubG Antenna.
