Unable to Read BLE Characteristic using QuecPython #131

I am using the QuecPython library to connect to a Bluetooth Low Energy (BLE) device (NRF51822) and read its characteristics. However, I am encountering an issue where I am unable to successfully read a characteristic after discovering it.

The specific problem occurs when I attempt to read the Battery Level characteristic (UUID: 0x2a19). While I can successfully discover the services and characteristics, reading the characteristic using the UUID or handle results in failure or errors.

Steps to Reproduce
Scan for devices using ble.scan_start().
Connect to the target device using ble.client_connect() with the correct address.
Discover all services using ble.client_discover_services().
Discover characteristics using ble.client_discover_characteristics().
Read a characteristic (e.g., Battery Level 0x2a19) using ble.read_characteristic_by_uuid(0x2a19).

Logs/Output
Here’s the relevant portion of the log that I’ve observed:
event_id : BLE_GATT_DISCOVER_CHARACTERISTIC_DATA_IND, status = 0
pair_len=7, len=8, data: b'\x07\x13\x00\x02\x14\x00\x19*'
handle=0x0013, properties=0x2, value_handle=0x0014
short_uuid: 0x2a19
characteristic_list len = 1

event_id : BLE_GATT_ATT_ERROR_IND, status = 0
errcode = 0x000a

event_id : BLE_GATT_ATT_ERROR_IND, status = 0
errcode = 0x000a

The characteristic with short_uuid: 0x2a19 is discovered successfully.
When I attempt to read the characteristic, I receive an ATT_ERROR_IND with error code 0x000a.
Expected Behavior
I expect that the read_characteristic_by_uuid(0x2a19) method should successfully read the Battery Level characteristic value from the device.

Actual Behavior
The characteristic is discovered, but when I attempt to read it, I get the error ATT_ERROR_IND with error code 0x000a.
The read operation does not return the expected characteristic value.
