BG770 doesn't shut down

IoT Modules LPWA Module
1

Per the doc “BG770A-GL Hardware Design LPWA Module Series” Version: 1.0.0 Date: 2021-01-28
Section 3.6.3.1 “Turn off Module through PWRKEY”
the mechanism is to strobe PWRKEY for 650-1500ms then wait for STATUS to go low.

I’m finding that, after performing the above sequence, STATUS never goes low.

Can you provide a known-good hardware sequence for shutting the modem down?

Thanks,

Hi Dave,

The latest HD will be publish in the next few days.

Sorry, I don’t understand your message.
Does that mean that the issue I described is a known bug that’s been fixed?
And what’s an “HD” ?

Yes, HD means Hardware Design.

So, does that mean that Quectel has identified this as a bug?
And, if so, is Quectel working on a fix?

Thanks!
