Good afternoon,
I'm Alberto Garau and I'm an engineer involved in a project where we use the wl1271.
We have the device running in SPI and we are observing a strange scenario. When the AP is placed 10 meters far from the device (-57db) it's very difficult scanning the ESSIDs and impossible to connect to them, the same behaviour doesn't happen when I move the AP close to the device. In that case I can scan the ESSIDs and I can connect to them easily.
Also in the mailing list linux-wireless@vger.kernel.org it has been suggested to us that probably we are facing a problem of calibration. Unfortunately we've found only poor documentation regarding the calibrator: http://linuxwireless.org/en/users/Drivers/wl12xx/calibrator#wl12xx_Calibration.
The calibration we have performed is the First Calibration listed on that web site and we have more questions:
1) is there any document explaining in depth all the parameters of the ini file TQS_S_2.6.ini
2) we used "./calibrator plt calibrate", what plt means ?
3) if we want to use the expert mode, we would have to provide <voltage>,<power>,<subband> and then tx_bip parameters, where we can found indication/documentation about that ?
4) is there any auto calibration ?
5) Could you please define the meaning of the "TxBip procedure" and when should be used ?
6) Could you please define the meaning of the "Tx Cont Procedure" and when should be used ?
7) Could you please define the meaning of the "Rx Stat procedure" and when should be used ?
Kind Regards
Alberto
