How to send a Payload to the Dragino LT-222222-L Device

The connection is fine, we are using the c8y-ttn-integration Cumulocity - The Things Network Integration

we now need to control the relais on the Dragino LT-222222-L Device with the Downlink Payload e.g. 0x030100 to set RO1 to close and RO2 to open.

How to do that?


Hi Mirko,

at the moment, the TTN Microservice only supports uplink messages. Sending downlink messages to TTN isn’t possible via the Microservice. This would require an update of the Microservice to support such downlink messages. This kind of extension hasn’t been planned yet.

Best regards
