Other Parts Discussed in Thread: CC2564MODN
This question is regarding the modulation type and test pattern values needed for FCC testing.
I have gone through the below links so far
- TI FCC Certification Guide
- CC256x FCC Testing Guide
- CC256x FCC Testing Guide for MSP430
- How to Certify your Bluetooth product
- CC256x VS HCI Commands
- Whitepaper
- TI Forum Post
I understand that I can use VS_Enable_FCC_Test_Mode() in Bluetopia SDK to put the chip in test mode.
int VS_Enable_FCC_Test_Mode(unsigned int BluetoothStackID, VS_Modulation_Type_t Modulation_Type, Byte_t Test_Pattern, Byte_t Frequency_Channel, Byte_t Power_Level, DWord_t Generator_Init_Value, DWord_t EDR_Generator_Mask)
Unfortunately, I am unable to figure out what is the significance of modulation type and test pattern. I understood from HCI_VS_DRPb_Tester_Con_TX (0xFD84) that possible values for modulation type are
- CW - Test pattern (second parameter, below) MUST be set to “All 1” or “All 0”
- GFSK (BR)
- π/4-DQPSK (2-EDR)
- 8DPSK (3-EDR)
- BLE
and test pattern are
- PN9
- PN15
- 5555 (0101 0101 0101 0101b)
- All 1
- All 0
- FOFO (1111 0000 1111 0000b)
- FF00
How can I decide which to use for my testing purposes? Is there a documentation available on when to choose what?
