But there are a few source examples i'm looking for.
i'm trying to make a program that tests as many functions and features as possible.

@ajb2k3 said in Purchased a m5StickV:

@xeon have you contacted M5Stack support about this? They should be available now

They verified the problem and will release a fix soon.

Glad to hear it.

I want a replacement.
i bought this device to get a task done.
it's going to.

@fpsychotic
Did yours get very hot while charging?

Yes, mine does get hot
BTW there is already a MK2 on its way.

1. Cant turn off
   Letting the battery run out seems to solve the power button.
   As it works fine again afterward.

2. Keeps bugging out after running a script in Maix Py ide
   Disconnect a reconnect

@ajb2k3
the problem came back.
i don't know how.

:(

After a reflash the issue is back?
Please email the M5Stack support people. something is defiantly not correct.

:(

Seems to be working as i hoped.
ty for not banning me.

used the latest firmware.
http://dl.sipeed.com/MAIX/MaixPy/release/master/maixpy_v0.4.0_52_g3b8c18b

do i need a script present ?

Holding the power button 6 seconds to try turn it off.
It keeps powering back on right away.

1. for the love of all that is holy.
   Tell people that sell your device the mic is broken and your looking to dump the project and your losses on it.

2. if you make a basic firmware, make sure the off button actually does what the manual says.

3. the manual covers less than some terrible products.

4. i can't even understand it's quirks.. connecting via serial reboots it??
   Then serial monitor is lost searching.

Starting to think i made a huge mistake.
such a awesome device.. so much potential.

:edit
reflashed stock.
still can't turn it off.
am i missing a trick?

How did you reflash it, what firmware did you use?
BTW the microphone issue only came up after the release and there was an announcement about the issue
