Hi Paopao,
I am in your same situation, I have been trying to communicate UHF-RFID-UNIT with Aton Lite and I don't know the right code.
Could you spend the code to start my project?

Thank you

Hello @Otofoto

are the aforementioned 25 minutes from a fully charged TailBat? That seems a bit short.

I've measured the power consumption of the Atom GPS kit (w/o sd card) and it takes about 100 mA. So it should not suffer from a premature shutdown due to consuming too little power as the shutdown current limit in the TailBat is about 45 mA.

The TailBat has a 190 mAh battery - so theoretically you should get close to 2 hours out of it.

Thanks
Felix

Hello @sgu

it looks like ATOM GPS is broken in current UIFlow. It doesn't work for me either.

That said, I found that I can use the GPS unit blocks instead (with default custom GPIOs).

@akscj Yes, you can. (Atom doesn’t have a battery though, so it’s not “charging”)

@sgu I don’t really know of a way to do this, maybe M5 could make a Unit USB. Or maybe me or you could design one.

@holofloh Ahh, thank you! I think I understand a little better now. I think I misunderstood exactly what an access point was supposed to do. I'll try your suggestions and let you know how it works.
Thanks again!

New CH552 firmware for Short-Wifi-Issue of M5Atom/Stick/TimerCAM/etc. : About 9 months ago

Many thanks to you for all the advice! I was indeed using a servo way too powerful for the atom. My mistake, I've learnt something :)

All the best to you

Hello @RolfF

It's a design mistake.
It is a basic mistake to add 5V to 3.3V system.
5V enters the RF circuit, causing deterioration or damage.
There are many cases where ATOM has already broken.

Wow, your balancing star is impressive!

I'm just playing around in UIFlow to see what's possible with this device.

Same problem with the CORE2, do you have a solution for this error with M5burner V3 under win10

This is normal if the Atom is not doing anything.
The Power chip expects a certain load to keep alive, it the atom is in standby then the load is too small and will cut out.

I also have an Atom GPS module and a LoRaWAN868 module. I plan to use both of them together to track my bike. I already got the GPS running using ESPHome. Unfortunately there seems to be no LoRa integration into ESPHome.
