RS21 causing reset

I am happy that it works and I am sorry for all wasted time because if this weird issue.

Sorry to open up an old thread, but this is slightly related I think and it might be useful to somebody in the future.

I have a setup with:

  • wifi rs21
  • t35 display
  • button
  • temp sensor
  • multicolor led
  • usb client dp

Was working beautifully, posting readings to thingspeak over wifi.

After that I decided to do some rewiring and mounting of the modules on a board.

Stupid enough, I used al long ribbon cable (the longest ones in the bag that comes with the spider kit) from the power module to socket 1. This also cause the board to reset upon a wifi.Scan().

Using a short cable sorted the issue for me.

Yes that is possible but in some cases, having good power solves this.

how are you powering your system?

Through USB (from laptop) and some old phone adapter (which only outputs 5V/1A).

I should use a powered hub instead, am I right ?
