Dear All:
Because the project needs to be certified, and one of the certifications is BLE fixed frequency, I would like to ask how BLE conducts fixed frequency testing. Is there related software or firmware provided?

Hi,
You can use the following lines of code in your project for continuous transmission of carrier wave.
void ll_hal_transmit_carrier_wave(uint8 channel)
{
uint16 u16temp;
CY_SET_REG32 (CYREG_BLE_BLELL_COMMAND_REGISTER, 0x48);
u16temp = channel + (5<<7) + (1<<13);
CY_SET_REG32((CYREG_BLE_BLELL_LE_RF_TEST_MODE), u16temp);
CY_SET_REG32 (CYREG_BLE_BLELL_COMMAND_REGISTER, 0x46);
}
Thanks
Ganesh

Can I specify the transmission frequency of BLE?

You can fix the transmission freq through setting the specific channel number in ll_hal_transmit_carrier_wave().
