Hi Victor, @vsowa12
I apologize that this took some time to get back to, but I have some more clarity on the issue.
The problem seems to be on the spotter’s ebox. I can measure 24V right out of the back of the ebox as depicted in @zack_j 's example when the spotter is first turned on and still showing yellow for its system. The system indicator turns to red after about 20 seconds however and the voltage then steadily drops down to roughly 3.4V. The spotter is fully charged, and otherwise doesn’t seem to have any issues.
Let me know what your advice would be, thanks for your time!

Hello Kora! @VernaMize
Could you please send me the logs from the Spotter SD card? If there aren’t any, could you put an SD card in the Spotter, turn it on and let it sit for about 10 minutes before gathering and sending the logs?
It sounds to me like there is an issue in the Spotter ebox and the logs may help me diagnose this.
Specifically, it sounds like there is an issue with the “bridge” in the Spotter ebox. The “bridge” is the board that allows the spotter to communicate with the other Bristlemouth nodes and also supplies the 24V. If there is an issue with this board, the Spotter may be shutting it down.
You can see if there is an issue with the bridge by connecting to the serial port of the Spotter and typing POSTpost to list the error states of the various Spotter subsystems. You can also try to send a bridge test to see if the bridge is able to pass its self test. The Spotter/bridge do this self test on boot, but if the bridge fails the test, the Spotter turns the bridge off.
Hope this helps!

Hi Victor,
Thanks for the quick response! I did take it outside and power it on for a while then downloaded the log folder. I did find this in the bridge file:
2024-06-19T18:34:18.703Z [BRIDGE] [INFO] Bridge Enabled
2024-06-19T18:34:24.703Z [BRIDGE] [WARNING] Ack timeout
2024-06-19T18:34:24.703Z [BRIDGE] [WARNING] Self test failed
2024-06-19T18:34:24.703Z [BRIDGE] [INFO] Bridge Disabled
2024-06-19T18:34:24.804Z [BRIDGE] [WARNING] Disabling bridge due to self test failure. Reboot to re-enable.
A bridge test through the serial connection returns a Fail as well.
I can still get you the full log file too if that would give you more information!
Another note too, the “POST” command was not recognized, thoughts?
Thanks!

Hi Kora!
Apologies, the command is case sensitive and I used all caps 
, when it has no caps. So try post out.
Yes please, send me the logs. I’ll take a look through and see if there is anything else I can gather from them.
Thanks,
Victor
Hi Victor,
No worries, here’s access to those files: SpotterLog - Google Drive
Thanks,

Hello Kora! @VernaMize
Thank you for sharing the logs! I think I know what is going on!
I see in the logs that the Spotter is currently on v2.14.1. Did you guys recently update the Spotter? Did you update the bridge too?
The Spotter and its Bridge (and anything in the bristlemouth network) all need to be on a compatible version in order to work properly. We are working on a doc that makes it clear what versions are compatible together.
So one thing you can do to test this out is to “downgrade” your Spotter to v2.9.0 using the link from this post Powering the dev kit from the spotter - #28 by vsowa12. Let me know if the bridge self test still fails after doing this.
Let me know ff you are interested in updating the Spotter, bridge, and devkit firmware and I can write up some steps on how to do that.
Best,
Victor
Hi Victor,
Thank you so much! I was able to downgrade the spotter to the v2.9.0 version and the bridge test passed! I was then able to connect to the devkit powered by the spotter. I’m working through guide 3 now, and I was wondering if I should be cautious updating the devkit? Knowing what versions are compatible with the spotter’s v2.9.0 would be reassuring going forward. Thanks for your time!

Excellent! I’m glad your bridge is working again.
We’re continuing to make progress internally on a firmware version management guide that includes a compatibility table. We look forward to releasing that publicly to answer these kinds of questions, but for now here’s the answer for your particular case. Spotter main deck firmware version 2.9.0 is compatible with Bristlemouth firmware versions 0.4 and 0.5. You can choose either one, but all Bristlemouth nodes, including the Bridge and your dev kit must be on the same version.
Cheers,
Zachary
