CC2640R2F: Can we change the frequency deviation?

Can I ask why you want to do this? By chaning this, I guess you will not be compliant with the BLE spec. anymore.

I know that it should be possible to do some changes to deviation using overrides, but I will need time to dig into it. Please note that if we can provide settings where you can change this, this will be settings that are not characterized or tested, and we cannot provide any other support on this other than giving you the overrides you can try.

Hi Siri,

We want to experiment different frequency deviation on our AOA project.

It will be great If you can provide the settings that can overwrite the default settings.

Thanks

Hi Siri,

Where should I add those settings?

Should I append the setting to the end of aoaRfRegTbl on AoA.c like this?

static uint32_t aoaRfRegTbl[] = {

    MCE_RFE_OVERRIDE(1,0,0,0,0,0),

    // BLE default overrides:

    HW_REG_OVERRIDE(0x6084, 0x05F8),

    // Locationing specific overrides

    0x00158000, // S2RCFG: Capture S2R from FrontEnd, on event (CM0 will arm)

    0x000E5164, // After FRAC

    0x02008004, // Use RFERAM

    0x03FF8008, // Use RFERAM

    SW_ARRAY_OVERRIDE(bleRadioPar, pLocationSetup, 4),

    (uint32_t) NULL, // Pointer to location packet definition table, set to NULL to disable locationing

    // Normal BLE overrides

    0x04280243,  //10 us added to the RF SYNTH calibration

    0x00FF8A43,  // set advLenMask to 0xFF to avoid ROM patch

// Set TX deviation to 160 kHz

0x00D800C3,

// Set RX filter to match 160 kHz deviation

HW_REG_OVERRIDE(0x50F0, 0x0300),

HW_REG_OVERRIDE(0x50F4, 0x5F18),

HW_REG_OVERRIDE(0x50F8, 0x0096),

    0xFFFFFFFF };
