Hi everyone,
I’m encountering a DOWNLINK_GATEWAY: TX_POWER error when sending Class B downlinks via ChirpStack to a Lorank8 gateway. The gateway logs show:
ERROR: Packet REJECTED, unsupported RF power for TX - 29
To address this, I edited the region_eu868.toml file and explicitly set the downlink_tx_power to 16 dBm, replacing the default -1 value:
[regions.network]
downlink_tx_power = 16 # Force 16 dBm for all downlinks
This seems to prevent the error, but I’d like to confirm:
Is this the correct approach to ensure the gateway accepts Class B downlinks?
Or is there a better/more standard way to align the downlink TX power with the gateway’s supported values?
Thanks in advance for any insights!
