    A few weeks ago I successfully flashed a smart socket with a BL 602 chip via Uart with version 1.17.643. If I now try to do an OTA update, the device resets and reboots with the old version. Do I have to pay attention to anything special to perform the update?

    So, the only way for the next update is to open it and flash it by UART again? I can't find a description for a workaround at your link.

    The speed throughput is the solution?
    By the way, I have no professional router like a Cisco to limit the throughput on a port.

    You just need to limit speed with chrome on website.

    Ok it sounds simple, but I have no idea how to do it.
    Is it easy to explain?
    Does it also work with Chrome browser on Android?
