I have a 6V 2W panel connected to VBUS for charging a Tenergy Li-Ion (2-cell 18650) 3.7V 5200mAh battery pack. I have seen some of the other posts about issues with the Power Manager software in v1.4.x DeviceOS and followed the recommendation to implement in the setup() function detachInterrupt(LOW…

@Tim-D , I’ve performed some recent testing with variable power supply (Current and Voltage), and with 6V Panels. Tests were performed using the Vusb pin. It appears that the Boron DPDM is going crazy during Sleep. After Calling enableDPDM(); during setup, the Boron will obey both Current and Vol…

@oddwires1 - I’m curious if there’s a workaround inclusive to Slee Mode?

The only workaround I’ve found so far is to revert back to DeviceOS 1.1.1. This DeviceOS works as expected charging both while awake and while sleeping… DeviceOS 1.2.1 doesn’t work at all (SOS+10 red blinks). DeviceOS 1.3.1 functionality is same as 1.4.x - OK while running but does not charge whe…

Revert back to 1.1.1, and then be F*****d dead in the water for the separate and distinct reason that the cellular is broken and won't reconnect prior to 1.3.0 I don't have the energy to describe how much wasted time, effort, and frustration has resulted on my end because Particle has destroyed the…

Hi Paul, Sounds like were are both in the same sinking boat right now. I suspect that the detachInterrupt code snippet that was proposed in other threads to correct the solar charging issues while the Boron is running is not required under 1.1.1 as we never needed it for the Electron and charging …

Any new info on this? Workarounds? I can confirm across several devices that I’m having the same issue. Small solar panels to power Borons that are asleep ~92% of their programming. It goes from constant ~60mA current being drawn from the solar (on a mostly sunny day) to flickering about 2pps. Happ…

No real news. No workarounds have been provided from Particle other than instruction to wait for 1.5.x to be released.

Some news here related to this issue although I haven't wrapped my head around exactly how to use the "fix" yet for our solar applications.
