PSoC 4 MCU

I start discovering my characteristics with CyBle_GattcDiscoverAllCharacteristics()  and get to the CYBLE_EVT_GATTC_READ_BY_TYPE_RSP event.

charReport = (CYBLE_GATTC_READ_BY_TYPE_RSP_PARAM_T *) EventParam;

charHandle =  charReport->attrData.attrValue[3] | (charReport->attrData.attrValue[4] << 8);

from code examples I can deduce the handle is in:

charReport->attrData.attrValue[3] | (charReport->attrData.attrValue[4]

and the UUID follows in charReport->attrData.attrValue[5] onwards, but is there any documentation on how the data is packed?

Hi Shane,

In the BLE_eventHandler.c  generated file for PSoC4 BLE, you can see there is a function(CyBle_ReadByTypeEventHandler) to decode the CYBLE_EVT_GATTC_READ_BY_TYPE_RSP event.

You can refer to this function implementation to get details on decoding the packet.

The packet received includes the CharHandle(2 bytes), properties(1 byte), Valuehandle(2bytes) and UUID(128 bit or 16 bit).

Thanks,

Ranjith
