LoRa while off battery #33

Closed Skipper-is closed 4 years ago

Skipper-is commented 4 years ago

I'm running the CubeCell board on a standard LiPo 18650 battery. I cannot get LoRa to transmit properly when running on LiPo. I am using the Ping Pong example, and when on USB power, it is working fine, but I unplug the USB, and power it by LiPo, and there is nothing. It is drawing power, and if I run another sketch (that just does the TX every 10s, followed by low power mode) it draws sensible amounts of current, followed by very low current... Is there a GPIO I need to pull high or low to enable the Radio when on battery?

There shouldn't be.

Can you confirm that the 18650 is fully charged and outputting a decent voltage? I am operating cubecell boards using 18650 cells with no issues.

It is currently running at 3.76v.

Yes, it shouldn't be...

We had tested each of the SH1.25 sockets before they were sent out. Is it possible that the positive and negative terminals of the battery are reversed?
