@happyuser I believe the Atom printer uses standard Rolls of 57x40mm Thermal Printing Paper. Quite cheap, you can get 4 rolls for about £7 on eBay.

Hello @tgprivate

glad to hear it worked. And thank you for reporting back.

Thanks
Felix

Hi Felix,
Thanks a lot.
Your solution also works for me.

Hi @felmue

Many thanks for your rapid reply and your helpful "debugging" questions.

My M5 Atom is working just fine now, even the GPIOs I thought I might have fried :-)

Cheers,
Philip

@felmue That makes sense, but (i think) the configuration box for other devices does not have a API key at the top, so maybe it's something to do with UART settings. (like being able to send UART commands during boot to change settings.)

Thank you very much for your reply. Very helpful.

Hello @LiRM35M4419

to be on the safe side I use a non PoE port while developing and with USB connected.

Thanks
Felix

Hello @MDCB

ok, you made me curious, so I've setup a Helium account and was able to join with a COMX.LoRaWAN868 module using a couple of AT commands. Unfortunately the COMX.LoRaWAN868 module has a different AT command set than the Atom DTU LoRaWAN base so the AT commands I used won't help you much. Also the COMX.LoRaWAN868 module is not covered in UiFlow which means I had to send the AT commands using the UART blocks. Essentially I had to choose LoRaWAN, OTAA, set DevEui, AppEui and AppKey (all three copied verbatim from the Helium Console) and then issue a Join command.

However what I can share is the output of the COMX.LoRaWAN868 module when I switch it over to LoRaWAN mode:

AT Rev 1.3 +AutoLPM=0 +LORAWAN=1 +KeepNet=0 +OTAA=1 +Class=A +ADR=1 +IsTxConfirmed=1 +AppPort=2 +DutyCycle=15000 +ConfirmedNbTrials=4 +ChMask=0000000000000000000000FF +DevEui=0123456789012345 +AppEui=0123456789012345 +AppKey=01234567890123450123456789012345

From that I think you might want to try a different class (A instead of C) and a different channel mask (0xFF instead of 1).

Thanks
Felix

Hello @Dieter_P

thank you - I appreciate you letting us know about the implication regarding power safe and usage of BLE and WiFi.

Thanks
Felix

@felmue ah okay, perfect! Thanks!

@ajb2k3 thanks for the tip but unfortunately I can't access the USB port in my setup, so I'll have to go through the pins anyway.

Hi @felmue and thanks for the quick reply.

I also looked at the datasheet and came to the same conclusion. It might be easier to find a fan that supports 0 rpm with lower (<10%) PWM duty cycles.

@sarahc because devices still use USB A

I am reporting that I was able to resolve myself.
The key to solving this problem was the "character string".
I assumed that the content sent by P2P was not a "string" but a "number".
It may be hard to see, but I will attach the screen created by UIflow.
I'm an amateur, but I'm glad I worked hard to solve it.

@gallopingsloth said in M5 atom lite connector.:

I learned all this the hard way after buying a bunch of now useless PH-2.0 4 pin cables.

What do you mean by Useless PH-2.0 4 Pins?

Grove cables are fully compatible with M5Stack products and HY connectors are compatible with PH as long as they are 2.0 pin spacings.
the only difference is that some are flat topped, some have locating fins and some have clips. I have a selection of various types and have even modded several including posting a guide and a comparison on the forum of the difference.

There was some confusion at one point with the White and yellow wires reversed but that has been solved and its not hard to swap the pins in the housing as again I have made a guide on it.

@felmue
thanks Felix!

i did’t care about time.
i'm tring to wait few minutes!
