debug battery powered node

  • Hello !

    I have sometimes tempertures nodes, powered by batteries, which are freezing ... If I reboot the node, all is working correctly ...

    How can I debug it ? If I connect the node to my computer, it will change the power input, so if it's a power related issue, I will not see it ...

    Do you have any idea ?

    Thanks !

  • Why not just connect the rx and tx pins and ground?

    This is how I debug my battery based sensors and run them from the battery. You even dont need the rx pin if you don't want to send commands to the node.

  • I didn't know it was possible !

    So : Vcc and GND from the battery, and TX, RX and GND to my usb serial adapter ?

  • Correct.
