Transmit power setting

Back in the December 2013 version of UM1695, there was a command to set the transmitter power of the module:

at+s.scfg=wifi_tx_power,42

In the firmware that I have, I get the response ''ERROR: Unrecognized key'', and getting the value of wifi_tx_power gives the same result.

Is it still possible to set the transmitter power? If not, what is the default setting equivalent? 0dBm? +18.3dBm?

Thanks,

Andrei

    tx_power configuration variable, and max_tx_power status variable too, were removed because of testing processes.

    Both variables will be again available in next FW: Release 3.1

    Through configuration AT command, it will be possible to set output power from 0 to 18 dBm. Factory default is 18 dBm.
