Starnote connects a few times then stop

Hardware

We’re using a Starnote 1.4 Developers Kit. Everything was working great and posting reliably to Notehub so we decided to do a real-world test in a no-cell area of West Texas. We placed our device in a location, saw that it was posting every 30 minutes and then drove away. It posted once more 30 minutes after we left, then stopped. When we picked it up 24 hours later it was still functioning and returned to cell area it delivered dozens of notes via Cell.

Our device is built around an ESP32.
Our RAT is set as “cell-ntn”.
We have a 1000 mAh battery AND a solar panel so battery power was good. Voltages were reported as healthy throughout.
Device was not locked up when retrieved.
Nothing but clear sky in this very flat part of west Texas.
Device posted 3x before never posting again so we don’t suspect an antennae or software issue.
We have tons of credits in our account so we don’t think its a billing issue.

Anyone have any suggestions on how to debug or what could be going on?

Hi @BillVW,

I’m very sorry but somehow this post fell through the cracks. Were you able to get this working again? If not, I have some quick ideas:

  1. Verify you’re on a relatively recent version of Notecard firmware (and update to the latest developer or LTS release if at all possible).
  2. Inspect the _health.qo events that were generated once it came back online via cell, I’d be very curious if there wasn’t something in there.

Thanks,
Rob

Hi Rob:
Thanks for following up. We were able to get things working with the new 9.1.1 release of the developer firmware. The combination of the firmware plus a more powerful battery/power supply to the starnote seems to have fixed things.

Thanks! - Bill
