My application on TTN is working fine, I can send uplink and downlink with my Dragino LG308 gateway to my LS01 and LHT65 end nodes.
But now I have built my MQTT Broker server on Raspberry Pi and my end node can send the uplink into my Raspberry Broker very well.
My problem is that I can’t send a downlink to my end node.
What data format should I use to send a downlink to my end node?
I’m not using TTN and instead I’m using a MQTT broker on the RPi. I have sent the “0xA601” function to it encoded as base64 but I get no response from the LG308 . In the LG308 log I get INFO~ [DNLK]Format error: when i try to sent some payload like pgE=
The topic on the LG308 that its subscribed to is also CLIENTID/# would this be correct?
the LG308 does appear to be receiving the instruction from mqtt but will not broadcast to LORA radios.
Any help is much appreciated,
