Hi RAKwireless team and community,
I’m working on a sports vest project using 15x RAK3172 modules (LoRaWAN OTAA mode) with a RAK5146-based gateway running ChirpStack v4 locally (Docker on Raspberry Pi CM4). The gateway is configured to US915_0 sub-band.
However, I’m consistently getting join failures with +EVT:JOIN_FAILED_RX_TIMEOUT. I’ve tried multiple configurations. Below are the full details of my setup and current status:
RAK3172 Configuration:
- Firmware version: RUI_4.2.0_RAK3172-T
- Mode: LoRaWAN, OTAA, Class A
- Region/Band: US915 sub-band 0
- AT Commands:
AT+NWM=1
AT+NJM=1
AT+CLASS=A
