DASH Button OTA Standalone

README.md

I don't get DASH button with OTA ins standalone working. ASAP I add the pwr_en PIN the boot process stops. When I re-connect to creator pro (just GND & reset) it works.

Feels like the battery is to weak or sth?

  This arduino program shows how to update AmebaIOT image via Arduino IDE.
  1) Upload the sketch to the creator pro baord for the first time and Reset the board Ameba.
  2) Part of the code starts an mdns service called " MyAmeba". Ideally the version of sketc is version 1
  3) Now edit this sketch. (Ex. the version number) and then reupload, this time instead of choosing USB port,
    use the IP based port that will show up in the port meny in the arduino IDE
  4) Once done Ameba would reboot. Check the serial port for the changes (eg version).

Hi,

As we discussed over @hackster i will look at the issue more closely and try to find why this would be the case. I have also emailed the RAK engineering team about the issue and lets see if they can also help us out here.

Hi,

About dashbutton's reset issue. the dashbutton's reset pin need weld a wire and connect to the creator pro board's RESET pin, then you can
push creator pro board's reset key to reset dashbutton.
or you can use power up reset, connect every wire ok except dashbutton's vcc pin, lastly connect dashbutton's vcc to creator pro and watch
the serial log if reset ok.
