Hello:

I am porting nRF51-ble-bcast-mesh to my project，I don't understand what's dbm in rbc_mesh_txpower_t.

Any help appreciated

Hi,

The dBm, or "decibel milliwatts" is here used with regards to the Radio TX power (output power of the Radio peripheral). You can set it to +4, 0, -4, -8, -12, -16, -20 or -30 dBm using the function rbc_mesh_tx_power_set()
