I am sorry but we still could not find any data loss in our lab. Can you try another test? Could you check if the byte count is wrong? You can see byte counts of both serial and TCP/IP sides on ezManager. Search your module and just click the [Status] button. You can find the SERIAL STATUS. - sio_rx: Received bytes from serial port - net_tx: Sent bytes to TCP/IP - net_rx: Received bytes from TCP/IP - sio_tx - Sent bytes to serial port Just check if the sio_tx count is the same with net_rx count and compare it with your data size.
