Hello,
i'm trying to detect a carrier wave at 2476Mhz.
i'm using the code example 'basic_ble' and i created a periodic event handler using clockP and tried to sample for carrier wave every 5 seconds.
- i call the function HCI_EXT_ModemTestRxCmd and set the parameter as 37 (2402 + (37 * 2)) = 2476Mhz.
- i add a delay using a loop or by using usleep (i tried both of them). i disabled the optimization inside this function by adding '__attribute__((optnone))'
- after the delay i read the rssi using the function HCI_ReadRssiCmd().
the rssi return always 0. i tried different frequency and all the same, i also add a command at the beginning of the code to increase the RX gain but it did not help (HCI_EXT_SetRxGainCmd(HCI_EXT_RX_GAIN_HIGH);)
the CW generator is ok and is generating a continuous CW at 2476Mhz and it was tested.
can you please advise me what i need to do in order to make it work ?
thanks,
Haithem,
