write error: Writing characteristic failed with status code 200

[brandomcombr]

Hi Community,

When I call the write method, I'm getting the error: Writing characteristic failed with status code 200

I saw that in the Device.kt file, there is this condition.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
            val statusCode = bluetoothGatt?.writeCharacteristic(characteristic, bytes, writeType)
            if (statusCode != BluetoothStatusCodes.SUCCESS) {
                reject(key, "Writing characteristic failed with status code $statusCode.")
                return
            }
        } else {
            characteristic.value = bytes
            characteristic.writeType = writeType
            val result = bluetoothGatt?.writeCharacteristic(characteristic)
            if (result != true) {
                reject(key, "Writing characteristic failed.")
                return
            }
        }

When I enter this first condition, do I need any additional permissions or need to call any other method besides connect to invoke write?

Status code 200 means ERROR_GATT_WRITE_NOT_ALLOWED. This means the peripheral device does not allow writing to this characteristic. You can check the characteristic properties using getServices
