Newest EB3A SOC mystery

s/n = EB3A2430003936084
IOT = v9046.04
ARM = v2114.06
DSP = 2113.05

What I thought was a Bluetooth Hardware problem on my newest (2025-July-02) EB3A turned out to be caused by the Bluetti app … now resolved

I have not been using this EB3A since I bought it a month ago because I thought it had a defective Bluetooth function and expected to get it replaced.

FYI:
I have discovered a problem with the Bluetti app running on a Samsung SM-T590 Tablet OS Version T590XXU3CVG5 / T59000XM3UF1 / patch level 2022–June-01. It was causing Communication problems.

Now that I can actually see on the app what it is doing, it has strange behaviour related to DC output and SOC that I will have to figure out (DC out = 110W +/- 5 with Grid Input = 155W +/- 5 shows SOC starting at 100% >> 90% after 45 minutes >> 17% after 50 minutes then I did a shutdown a minute later when it read 9% … then removed DC output connection, power on & SOC = 9% increasing 100% with 90 seconds) … I plan to attempt to re-calibrate the battery first to see if this strange behaviour stops.

Anybody else seen this kind of behaviour? If yes, did you find the cause? and the fix?
