3.2.3 - Selection of the radio board emission power
Compatibility: This functionality is accessible only on WaveCard 25mW.
It is possible to adjust the radio board emission power of WaveCard, according to the following table (by
default, the level is configured to 14dBm):
Parameter value
0x0A
0x09
0x08
0x07
0x06
0x05
0x04
0x03
0x02
0x01
0x00
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:

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.
