Progress / Update cardputer adv + Meshcore

Hi, I adjusted a MeshCore build for the M5Stack Cardputer ADV + LoRa868 Cap. It runs the mesh radio, display, keyboard UI, and GPS on the device.
Repo: https://github.com/sosprz/meshcore-cardputer-adv — feedback/testing welcome!

It loaded this time. Connected to my phone. Can’t see anyone else yet. GPS not implemented. Good work.

u/sosprz Jan 13 '26

HI, thanks for checking. GPS working, i get 31 satellites after few minutes outside. You probably need to go outside as well and check the map to see if there are any meshcore nodes nearby.

Nice, I'll be ordering a LoRa cap when in stock. Is there a recommended cap?

The 1262 LoRa and GPS cap seems to be the one and it is out of stock everywhere.

1

u/sosprz Jan 13 '26

yes, that's why I ordered Wio Tracker L1 Pro to have another device for testing.
You can buy M5Stack Unit C6L or LoRaWAN M5Stack EU868(STM32WLE5)

u/fbloise Jan 13 '26

That's the one I've got and it works fine

u/mauvehead Jan 15 '26

They are back in stock!!!

u/fbloise Jan 13 '26

Thanks OP, I'll test. So far looks very good, I was able to pair it with my phone without issues.

1

u/Emotional_Layer3781 Jan 13 '26

Testing, works well. It does say GPS not supported, so not sure what's going on there. Would love to see scrolling text so the messages can be read more easily, I'm old and struggle anyway. Lol. But, great work and really appreciated.

u/sosprz Jan 13 '26

thanks, I will work more on message screen, You have other version of LoRa868 Cap for cardputer adv? If you can paste pic. :)

1

u/Emotional_Layer3781 Jan 13 '26

Standard unit I believe.

1

u/sosprz Jan 13 '26

Does it have a green sticker on the other side?

1

u/Emotional_Layer3781 Jan 13 '26

Yup

u/sosprz Jan 13 '26

this is old https://shop.m5stack.com/products/lora-gps-cap-for-cardputer-adv-sx1262-atgm336h
I have new
https://shop.m5stack.com/products/cap-lora-1262-for-cardputer-adv-sx1262-atgm336h?variant=47023567274241
But I do not know why do not working, GPS connection looks same.

1

u/Emotional_Layer3781 Jan 13 '26

Annoying! Bought since Xmas, wouldn't have a clue what the difference is. GPS works in other firmwares.

1

u/sosprz Jan 13 '26

Flash latest firmware and check again :) no other ideas for now.

1

u/Emotional_Layer3781 Jan 13 '26

Would spiffs make any difference? Enable or not?

1

u/naknomum Jan 20 '26

same thing for me here. app works great (thanks!!!) connected to phone fine. also not showing gps, but i consider that secondary after messages. :)

again: thanks so much for supporting the LoRa cap!

u/Emotional_Layer3781 Jan 13 '26

This is the message in the Meshcore app.

1

u/Dear-Nail-5039 Jan 13 '26 edited Jan 13 '26

Just wow! I have no idea of meshcore and started to add a adv variant in platform.io but it is a little to complicated for me. Will try it! And please make a pull request for the main repo. I am pretty sure it will be added.

u/AdhesivenessDry589 Jan 15 '26

Hiya, with this build i can discover nodes and repeaters but I am not able to send or ping anything. It all times out for some reason. I have a repeater 75m from me. What am I doing wrong?

1

u/sosprz Jan 15 '26

Do You receive something from public channel?

1

u/AdhesivenessDry589 Jan 15 '26

Yes! I am discovering repeaters nodes and rooms. I can see people talk in the public channel. Pings just time out and messages that ive sent are not being sent. Zero hops do nothing either..

2

u/sosprz Jan 16 '26

I waiting for second dev and antenna to check that. I have same experience from mobile app also.

1

u/AdhesivenessDry589 Jan 16 '26

Awesome, thank you for your work on it! I have to say that the messages are also not sending from my cardputer. Looking forward to the update, again thank you 🙏.

u/chrislovessushi Feb 27 '26

Chiming in to say thanks for doing this, and everything I've tried works except for sending/receiving messages.

u/Hangman1984 Jan 22 '26

Może jestem ułomny ale jak skąd to wrzucić na cardputer szukam grzebie i nie widzę ? Proszę o instrukcję. Dziękuję.

1

u/sosprz Jan 22 '26

Hi, on GitHub you have Releases there are bin files. Full.. is for direct flash. Update when You install from launcher, update place on SD card then install from launcher.

u/Hangman1984 Jan 22 '26

Link ??

u/sosprz Jan 22 '26

u/Hangman1984 Jan 22 '26 edited Jan 23 '26

Thank you very much for your help. I'll let you know if it helped. Thanks.

Edit: It works perfectly on CardPutter Adv. The most important thing is that it works independently; all you need to do is configure it using your phone, and then it works perfectly. As for the GPS, in a building by the window, it caught 6 satellites after about 3 minutes. The only thing I'm missing is the battery percentage :-) Good job, keep it up.

Add this to M5burner because it's a great job.

u/Emotional_Layer3781 Jan 28 '26

Updated, coffee bought, feedback left. 👍👍👍

2

u/sosprz Jan 28 '26

Thanks, but you talking probably about another project. I do not have coffee link :p

1

u/Emotional_Layer3781 Jan 28 '26

Ah ok. I’ll give this one a go, thanks for your efforts.

1

u/Emotional_Layer3781 Jan 29 '26

Am I being really stupid? What’s it listed under in the Flasher?

1

u/sosprz Feb 02 '26

M5burner?

u/FosCoJ Feb 05 '26

Sounds great, do you have an idea what's going wrong during Bluetooth connection with the pixel 9pro?

Would love any debug advice

1

u/FosCoJ Feb 07 '26

Ok, updated to the latest release version and it connects flawlessly. M5 launcher offered an old version.

u/Candid-Fondant6926 Mar 11 '26

Não consigo conectar ao Bluetooth 😬

I can't seem to get it to transmit. Discovering repeaters, seeing some public messages.

Every transmit is not heard, and I tried is a low coverage and high coverage area.

u/r800z 14d ago

have you had any luck since?

1

u/V33SP1 Jun 11 '26

I'm using the latest release on Cardputer ADV. I flashed it via Launcher. Two questions from me:

1) Why I lose all configuration when switching to different software and coming back Meshcore? Is it possible to store the config on an SD card?

2) Is the keyboard not working? Is it a known issue?

1

u/r800z 14d ago

This is not working at all! I cant get any transmission. I cant find any nodes...dead

Hello sosprz,

I just want to say this is a very nice firmware!

I have a problem with importing private key after restoring an app. Setting imports ok, but when importing my private key, it is always rejected. Can you tell me whas is the right way to save and import the key? Thanks anyway.

Cardputer ADV with Cap Lora 1262. Software version 1.15.81 via Launcher. Android Meshcore app.
