What additional data should be contained in advertising data as best practice ?
(AdFlags, ServiceList, ClassOfDevice, ManufacturerSpecificData, TxPowerLevel)

What is the purpose of Incomplete Service List ?

Should be use to add more 128b UUID's ?

app_config.c
/* Scanning and Advertising Data */
static const uint8_t adData0[1] = { (gapAdTypeFlags_t)(gLeGeneralDiscoverableMode_c | gBrEdrNotSupported_c) };
static const uint8_t adData1[] = { 0xE0, 0x1C, 0x4B, 0x5E, 0x1E, 0xEB, 0xA1, 0x5C, 0xEE, 0xF4, 0x5E, 0xBA, 0x50, 0x55, 0xFF, 0x01};
static const gapAdStructure_t advScanStruct[3] = {
{
    .length = NumberOfElements(adData0) + 1,
    .adType = gAdFlags_c,
    .aData = (void *)adData0
},
{
    .length = NumberOfElements(adData1) + 1,
    .adType = gAdComplete128bitServiceList_c,
    .aData = (void *)adData1
},
{
    .length = 8 + 1,
    .adType = gAdShortenedLocalName_c,
    .aData = "FSL_OTAC"
}
};

gapAdvertisingData_t gAppAdvertisingData =
{
NumberOfElements(advScanStruct),
(void *)advScanStruct
};

There is a way to assert the length of adv data package ?

size = NumberOfElements(advScanStruct); assert( size <= LIMIT ) ?
Or compile time check ?
LIMIT should be 31 bytes ?

The value value_device_name should be the same as gAdShortenedLocalName_c aData ?
gatt_db.h
PRIMARY_SERVICE(service_gap, gBleSig_GenericAccessProfile_d)
    CHARACTERISTIC(char_device_name, gBleSig_GapDeviceName_d, (gGattCharPropRead_c) )
        VALUE(value_device_name, gBleSig_GapDeviceName_d, (gPermissionFlagReadable_c), 19, "FSL_BLE_OTAP_CLIENT")
    CHARACTERISTIC(char_appearance, gBleSig_GapAppearance_d, (gGattCharPropRead_c) )
            VALUE(value_appearance, gBleSig_GapAppearance_d, (gPermissionFlagReadable_c), 2, UuidArray(gUnknown_c))
    CHARACTERISTIC(char_ppcp, gBleSig_GapPpcp_d, (gGattCharPropRead_c) )
        VALUE(value_ppcp, gBleSig_GapPpcp_d, (gPermissionFlagReadable_c), 8, 0x0A, 0x00, 0x10, 0x00, 0x64, 0x00, 0xE2, 0x04)

Thank you,
Lucian.
