Dear Sir/Madam,
We are trying to perform the FCC BW requirment test using the CC2564 module with the below SW configuration.
1. Configured the CC2564 mudule in BT classic mode.
2. Using the "Bluetopia" Stack.
3. FCC test is triggred using the API "VS_Enable_FCC_Test_Mode" with the PN9 test pattern and GFSK modulation.
With the above test setuo we are achiveing only 480~490KHz BW. Is it correct BW measurement for FCC requirment in Bluetooth classic mode?
The below statement "The minimum 6 dB bandwidth shall be at least 500 kHz" is only applicable for the BLE mode?
The below is the output for the PN9 test pattern for -3dBm power:
