Downlink_Tx_Power

Setup and configuration
1

Dear Community,
What MAC command is sent by the Network Server when we set a particular downlink_Tx_power in the Chirpstack_Network_Server.toml file? and how can we get confirmation that the command is succeded and the gateway is transmitting at that power level?

Thank You,
Shubham

The downlink tx-power is not related to any mac-commands, it is used to define the tx-power that the gateway will use to transmit the downlink.

Then how does the NS instructs the gateway about the downlink_Tx_power…is there a field in the downlink data message itself to do so?

It is part of the txInfo element in the downlink gateway command: chirpstack-api/gw.proto at master · brocaar/chirpstack-api · GitHub.
