I have a number of devices which, after running normally for a few days, stop accepting a charge. This is causing devices that have run on Solar with STOP mode sleep to discharge their batteries even when there is solar or DC-In voltage to charge. To fix the issue I have to: Turn off the device D…

@ScruffR , Sure, but I checked the feature and bugfix list and saw no mention of anything to do with the setPowerConfiguration API. Chip

True, but some of the peripheral changes might play into the issue (e.g. I2C changes or even ublox settings). Just a stab in the dark, but shouldn’t hurt :blush:

When looking into these types of issues, I suggest getting a dump of the actual PMIC state. Something along the lines of: void loop() { { PMIC power(true); Log.trace("Current PMIC settings:"); Log.trace("VIN Vmin: %u", power.getInputVoltageLimit()); Log.trace("VI…

Interesting Graphs Chip ! All 3 devices exhibit a constant slope during discharging for the diurnal cycle, as expected. But all 3 devices show an immediate increase in discharging (steeper slope) prior to the failure. The next morning the PMIC does source power during Daylight (flattens out) , bu…

@Rftop , Very interesting observation. In fact, I see this pattern in a few more devices: [image] An even in this one where the steeper slope preceded an unusual increase in charge: [image] I wonder if I could issue a pmic.resetWatchdog() to a device showing this behavior to get it working a…

[image] chipmc: I wonder if I could issue a pmic.resetWatchdog() to a device showing this behavior to get it working again until I figure out what the issue is. You can disable it, but I don't think it's the culprit.....since the increased demand precedes the Charging Issue.

Going to try using the PMIC commands directly and disabling the setPowerConfiguration API. conf.feature(SystemPowerFeature::DISABLE); System.setPowerConfiguration(conf); pmic.begin(); pmic.setInputVoltageLimit(5080); pmic.setInputCurrentLimit(900) ; pmic.setChargeVo…

Thank you and I will incorporate this into my test device here in my home office. I looked for potential solutions to collect this data from remote cellular connected devices but this does not seem to be practical. There does seem to be a couple 3rd party log handlers but based on the time since t…

@chipmc any word on this chip? I think I’m having the same or a similar issue. It works great for a while then sucks tons of current and doesn’t charge. I’m not sure about the enableDPDM line too, isn’t that really for usb power negotiation? Don’t take my advice though, I’m sitting in my basement w…

@ccunningham , I don’t think we have closed on this yet. I have a support ticket and am getting help from the Particle support folks. If you are not going to use a USB cable to charge your Boron, you can leave the DPDM stuff out. I think we made some progress on resetting the PMIC in this thread,…
