ATT_ReadReq or GATT_ReadCharValue

Victor Ting

If I wanted to read an attribute value and I know the attribute handle, is it better to use ATT_ReadReq() or GATT_ReadCharValue()?

Does GATT_ReadCharValue() eventually just call ATT_ReadReq()?

    In answer to your question, yes GATT_ReadCharValue does call ATT_ReadReq. Other GATT sub-procedures are not as simple, as they may call a series of ATT commands and perform certain behavior based on the responses from the peer device. If you want to properly use the full BLE stack, GATT sub-procedures should be used rather than directly calling ATT functions.
