    @opichals I too have had success with WAVGAT, haven't stumbled across WeMos though, but checking that page, and beneath the Overview tab:

    Package Included:
    1×WeMos D1 mini

    Maybe there is a subtle difference in board design? Is there underside silkscreen that definitively states it isn't a WeMos brand? You then might consider a refund 'Not as Advertised' request, as title doesn't match what's included doesn't match image.

    EDIT:
    Oops, didn't really understand the 'Tasmota' reference, before I posted

  • The fact that the Tasmota firmware works without any issues makes me think about what Espruino needs changing to support these particular ESP8266s as well.

  • So it is not running yet - correct?

    maybe there are some wrong setting in user_rf_cal_sector_set()

  • No, it is not. I was too optimistic when I was able to connect to it.

    The wifi.connect() call consistently crashes it.

    @MaBe I haven't looked into these addressing specifics before. I have tried flashing it as 1MB/2MB and 4MB boards and none of those seemed to help.

    Any suggestions?

  • You could try a older firmware, pick one from here

  • I think I tried 1.99 (for 4MB) and had the same issue. Let me get back to it once I have some time again to spend on this. Perhaps there was something I missed in those tests. It was a lot of combinations in a single weekend.

    While this is three years old, and on a WAVGAT brand, here is the exact commnd I used for the version specified then. The device worked last time I powered up, over a year ago!!

  • Did some test with different board

    1. poor usb to serial chips or driver implementation need slow baud rate like 115200
    2. flash modes like qio/dio are esp-vendor-board specific

    Workaround for 1. is to use a usb to serial adapter directly connected to TX, RX and GND to use higher baud rates.
