Power level (dBm) 14 12 11 9,7 7,9 5,5 3,3 2,1 -0,3 -4 -16
Remark : Output Power values given in the table above are approximative ones (±2dBm).
Indeed,Wavecard Radio Board is optimized for 25mW radiated RF Power.
The modification and reading commands of the power level, are as follows:
CMD NAME DESCRIPTION
0x44 REQ_CHANGE_TX_POWER Request to update radio board emission power
0x45 RES_CHANGE_TX_POWER Response from the radio board to the emission power update
0x54 REQ_READ_TX_POWER Request to read radio board emission power
0x55 RES_READ_TX_POWER Response from the radio board to the emission power read
Remark : In the command byte coding, the Response frame type are taking the Request command byte value
with the LSB bit set to 1.
