static let kBLEService_UUID = "6e400001-b5a3-f393-e0a9-e50e24dcca9e"
static let kBLE_Characteristic_uuid_Tx = "6e400002-b5a3-f393-e0a9-e50e24dcca9e"
static let kBLE_Characteristic_uuid_Rx = "6e400003-b5a3-f393-e0a9-e50e24dcca9e"

//To notify
peripheral.setNotifyValue(true, for: rxCharacteristic!)

//To write data
blePeripheral.writeValue(Data(byteArray), for: txCharacteristic, type: CBCharacteristicWriteType.withoutResponse)

Not received any updates on RX side. I have checked characteristics properties for TX(write, write without response), for RX(notify).

I had a similar issue, but it was being caused by my message exceeding 20 bytes. Try splitting up your longer messages, as I believe you're hitting the max packet length.
