How do I use SRU_BT to have TX carrier power output in regulation tests for the MSD40NBT/SSD40NBT in the WINCE/WM platform?
To have BT TX carrier power output for the MSD40NBT/SSD40NBT, use SRU_BT and run HCI command as follows and to have unmodulated signal, set the mode as 0 as below:
HCI Command:
14 FC 07 00 02 01 00 08 04 00
