@kylecat1 Hey,

yes its could be old FW burned, i think i was the same with my unit,
go to https://docs.m5stack.com/en/quick_start/unitv2/update
and follow the guide.

Hi,

Which is the minimum time between snapshots? Can I take and send a picture per second?

Thanks in advance!

if the camera keeps work send the video stream. it would not have a long time, the battery is small, that is the reason why we recommend use this product for the timer shooting situation.

Hello @anvup1

Searching through the SIM7020G AT command document the command AT+CCINFO is not listed. I don't think that command exists for SIM7020G.

For most commands you can check if they are supported by adding =?. E.g. AT+CCINFO=?. Does that actually return OK?

Thanks
Felix

Hello @felmue ,

Thanks for your response, Yes, I also saw this Schematic and that's why thought to confirm from M5Stack before proceeding.

Thanks

I faced common issue with core grey module, made a couple of titles and was feeding formatted data from light sensor and envII module. Had to spend some time playing with delays to make it work properly but was blaming raped micropython build.

Long things short, don't try to understand it, try adding delays.

In UIflow add rgb strip unit, set number of leds and program.
It's not that hard in uiflow (which outputs to MP) the only issue is the power that can be supplied from the atom to strip. You made need to connect a second power supply to just the strip.

Answering my own question. This was trivially simple in my code. My code was doing deep sleep in the setup() function. When waking up from deep-sleep the setup function is called again. But if the device is powered by USB then deep sleep fails and we will reach the loop() function. So any special code that I want for USB power should simply be put in loop().

Thanks to both :)

@ajb2k3 : as written also by @felmue I want to power all my system with 3.3V so there won't be around any 5V at all !

Of course I need to check the specific schematic in order to understand what to bypass, but my question was if the white enclosure of M5Stack modules (like the I2C hub, or the heart rate sensor) can be easily open - without damaging / breaking them - or not (is there something like a screw?).

Any clue about that?

thanks!

Hello, have you tried putting to sleep mode? how long you had the timer camera F ? it sounds like the battery is drained, have you tried to charge it for about an hour or so?
