Hi,
Hello,
I am working on a project using LoRa 2.4GHz and need some assistance with configuration and performance.
Here are the details of my setup:
Development Environment: SES 8.18, nRF5 SDK Version 17.1, nRF52832.
Transceiver: E28-2G4M12S (SX1280).
Gateway: MikroTik wAP LR2 kit.
chirpstack --version 4.9.0
chirpstack-gateway-bridge version 4.0.11
I can send uplinks to the gateway, but I get the following error in the ChirpStack Gateway Bridge logs:
´nov 21 10:32:51 santos chirpstack-gateway-bridge[35649]: {“addr”:{“IP”:“192.168.88.1”,“Port”:57128,“Zone”:“”},“data_base64”:“AgGpAJNX70hTWDU5eyJyeHBrIjpbeyJjaGFuIjoxLCJjb2RyIjoiT0ZGIiwiZGF0YSI6IiIsImRhdHIiOiJTRjEyQlc4MTIiLCJmb2ZmIjotMTkwNTQ2LCJmcmVxIjoyNDc5LjAwMDAwMCwibHNuciI6LTI0LjAwMDAwMCwibW9kdSI6IkxPUkEiLCJyc3NpIjotMTA0LCJzaXplIjowLCJzdGF0IjoxLCJ0bXN0Ijo0NDUwNjc1NDR9XX0=”,“error”:“get uplink frames error: backend/semtechudp/packets: get uplink frame error: backend/semtechudp:packets: invalid CodR: OFF”,“level”:“error”,“msg”:“backend/semtechudp: could not handle packet”,“time”:“2024-11-21T10:32:51-03:00”}`
