Mike,
Thank your for your quick response.
I am trying to use Class C operation without the ACK or waiting. The same way as you mention I want the mDot::send() return immediately after data has been transmitted, then transmit the next one without waiting previous ACK.
I have set the mDot::setTxWait(false) and mDot::setAck(0). But it still takes longer time, 13s to transmit 1K. Additionally, I can still receive data from the getaway when I disable the RX window(Rx date: 1up). Check the detail terminal output below. The same situation happened when I tried to set AT+ACK=0 and AT+TXW=0 using the newest version of the mDot AT command firmware.
When I used the same code with the newest libmDot-mbed5 and mbed-os, it tends to re-transmit more frequently than the old version(it fails more in the first transmission).
Thank you for your help,
Wesley
