I would like to know a command/method to determine if the battery is connected to a Boron. If you disconnect the battery the cloud seems to figure it out by not displaying the battery voltage. If I use the command fuel.getSoC(), I get a voltage weather the battery is connected or not. I considered…

Have you tried searching the forums for similar topics? [image] Argon check power source? Firmware Yes, all of those are available on the Argon and Xenon. #include "Particle.h" SerialLogHandler logHandler; char lastMsg[128]; unsigned long lastPublish = 0; void setup() …

Yes but narrowed my search to Boron. I have had issues with trying to use commands/methods for other devices. I understand the power monitoring on Boron (hardware) is different than Electron and Argon. But will give that a try. And also look at your code. Thanks!

getVCell() may work for this, but I have not tried it on a Boron with no battery connected. https://docs.particle.io/reference/device-os/firmware/boron/#getvcell-

For the Boron I haven’t fully figured out all the different power management states, it’s a little bit tricky. Some friends are fuel.getVCell(), fuel.getSoC(), and pmic.getSystemStatus(). Here’s some code of mine that runs in loop() and displays some info. Not pretty or polished, but a starting poin…

This code for the Electron will also work on the Boron for determining if a battery is connected: [image] When is Electron Powered By Battery General This version is much better. It uses the BAT_INT_PC13 interrupt to detect the rapid switching between fast charge and cha…

This method installs an interrupt handler that ends up firing 30x per second, I’m not sure that’s so cool… Update: I tried it out and it’s not working. My Boron does not rapidly switch between fast charge and charge done when there is no battery (the charge LED also does not flicker). My code prope…

Oh, wait, do you have a Boron LTE? That code probably won’t work right because the Boron LTE has other code to turn off charging when there is no battery so the LED doesn’t flicker all the time. That’s done because the battery is not required on the Boron LTE. The two things are probably interfering…

OK, this is a much better way to do it, using the DiagnosticsHelperRK library. I added a new example to the library for power source: #include "Particle.h" #include "DiagnosticsHelperRK.h" SerialLogHandler logHandler; unsigned long lastPublish = 0; int lastPowerSource = -1; void setup() { Seri…

Sorry for the delay. The best solution I found was a combination of using getVCell() to determine if the battery is connected and DiagnosticsHelperRK.h for detecting the power source. I found that with the battery disconnected on a Boron LTE the value returned was close to zero, (0.06 disconnected…

Yes, it’s a Boron LTE.
