Hi, I am working on a Boron LTE that takes a differential air pressure reading every 60 seconds and spends the rest of the time in standby (SLEEP_NETWORK_STANDBY). For some reason soc seems to be “stuck” and is not updating. I have reviewed my code multiple times and tried adding short delays with …

@ielec , Thank you for engaging with me on this issue. After a couple days of collecting data, I am less sure that there is an issue. Three factors may have combined to create the impression that there is an issue with Sleep and Power Management in deviceOS@1.5.0. The three factors are: dramati…

@chipmc @Rftop Can either of you confirm the low power consumption claims with the new 1.5.0 firmware on the Boron or Argon as accurate? I haven’t had time to verify the improvements yet but would love to know what you guys are seeing as far as battery runtime improvements.

@chipmc , after ignoring the issue associated with running an Electron on battery until dead for too long, I’ve revised my several applications to put my Electrons to sleep for a couple hours when the state of charge falls below 50%. I eventually disconnect the battery when the state of charge falls…

@ctmorrison , That is my current approach and it seems to be working. Also if possible, run this command before the device reconnects to Particle as the power demands of the cellular radio could impact the battery reading. Like you, I send my data to Ubidots and will be watching this issue to see …

[image] RWB: @chipmc @Rftop Can either of you confirm the low power consumption claims with the new 1.5.0 firmware on the Boron or Argon as accurate? I haven't yet. It's on my "To-Do" list as soon as I get some free time.

@RWB , Results are posted here. [image] Boron - Sleep 2.0 Examples and Power Savings Firmware Now that deviceOS@1.5.0 is (almost?) here, I have been working to field my first Boron based devices. First, I build a new carrier board and shared the results here: Then, I s…

@chipmc , based on your additional Sleep 2.0 testing (awesome work thank you), do you believe that SOC with sleep is behaving as intended or there could be an issue?

@Backpacker87 , To be honest, I am not sure but I am having a hard time finding a clean way of proving there is an issue. I have a device on my desktop which I put an external load on and I am seeing updates to the SOC. I also have tow identical devices deployed in local parks with solar panels an…

@chipmc , I keep ending up in the same boat. Each time I think I found the smoking gun that soc is not working, something changes to make me think it is working. Check this out though with solar boron test over the weekend: Bat. voltage via fuel.getVCell() as @Rftop suggested. [image] soc over ex…

Its been a while since I read the datasheet for the Fuel Gauge, but the SOC is a calculated value based on many variables. The Fuel Gauge will gather data and eventually return a correct assumption about the charge condition of the Li-Po. The Fuel Gauge doesn’t have the luxury of taking a voltage…

@RWB,

Results are posted here.

Please take a look at the results and my approach.

Thanks,

Chip
