write
suspend fun writeCharacteristic(serviceUuid: UUID, characteristicUuid: UUID, value: ByteArray): Boolean
Writes a value to a characteristic on the connected BLE device.
This is a suspend function that will complete when the characteristic write operation finishes. The device must be connected before calling this method. The write type used depends on the characteristic's properties and the underlying implementation.
Return
true if the write operation completed successfully (GATT_SUCCESS), false otherwise (e.g., characteristic not found, device disconnected, write not permitted, or GATT error).
Parameters
service
The UUID of the GATT service containing the characteristic.
characteristic
The UUID of the characteristic to write to.
value
The ByteArray value to write to the characteristic.

Throws
If called when the device is not connected (depending on implementation).
