Command Required to enable FTM in BC66 module at the frequency of 847MHz

Hi,

We need the commands to enable the FTM in the BC66 module at the frequency of 847MHz and power of 23dBm. We already have the commands but they are for the 1830MHz and power of 23dBm.

The sequence of the commands is as follows:
AT+CFUN=0
ATMCALDEV=1
ATMCAL=“NRF”,0,21,8,“L7C47000000000017”

Can you please guide us how we can update the frequency from 1830MHz to 847MHz for the BC66 module.

Thanks.

It is not 1800 MHz, but EARFCN 1830 which translates to 1950 MHz. Use can use this calculator. Value 7C47 is actually 18300 in big endian. You can use the same EARFCN calculator to look for other frequencies.
