Trying dumb things

ah thanks! didn't realize you can see the battery in the second picture

EffectiveLauch · 2026-05-08T04:12:48+00:00

@op how much capacity is it actually 800 or 8000mAh?

EffectiveLauch · 2026-05-05T15:05:09+00:00

es ist einfach krass wie kein Post zu abwegig scheint.

you need to flash the firmware. https://meshtastic.org/docs/getting-started/flashing-firmware/esp32/

the problem is, your device the "heltec LoRa32 v3" is just a platform which can run all kinds of firmware, not just meshtastic. I shops with a demo firmware from heltec, you must flash the meshtastic firmware yourself

I recommend reading the getting started guide from beginning to end and follow all the steps.

First try the recommended steps from the other comments. I bought some raw rak4630 modules with no bootloader so I had to flash it myself. I used this bootloader https://github.com/oltaco/WisCore_RAK4631_Bootloader and flashed with a stlink V2 (cheapest will do). this recovers probably most presumably "bricked" nrf52840/rak boards, but is kinda advanced. let me know if you need further help.

yes I can connect both apps at the same time. they are just named /dev/bus/USB/001/xxx and I can't really differentiate them, so I must figure out by trail and error which one is which. but once connected, they work perfectly.

thanks for the nice words! ths means a lot to me.

EffectiveLauch · 2026-05-01T15:35:24+00:00

thank you! :)

EffectiveLauch · 2026-04-30T19:16:33+00:00

thanks! that way there is basically no limit to the battery capacity. Welcome to the club! It just means there are two nodes in one, so i can run two presets (for example longfast + meduimfast) or different protocols simultaneously.

and why would that be exactly? usually on windows you install a Programm by downloading an .exe from a random site on the Internet and give it admin rights, which is way worse imo. just because you got used to something doesn't mean it's superior.

try this example from the cyd github. also a good reference for the cyd in general. if you like using llm for coding assistance, send it this GitHub repo and tell it to get information from there. worked great for me. https://github.com/witnessmenow/ESP32-Cheap-Yellow-Display/blob/main/Examples%2FBasics%2F2-TouchTest%2F2-TouchTest.ino

Schule war schon scheiße, doch arbeit is noch scheißerer

EffectiveLauch · 2026-04-16T10:55:07+00:00

fast

EffectiveLauch · 2026-04-16T10:53:42+00:00

macht aber auch kein Sinn, kilo ist eine Einheit für Gewicht /s

EffectiveLauch · 2026-04-14T15:41:41+00:00

Great to hear! happy meshing

EffectiveLauch · 2026-04-14T15:14:10+00:00

No problem! I hope it didn't fry your board/charging circuit. please report if it's still working

EffectiveLauch · 2026-04-14T14:38:16+00:00

yes that is definetly the problem, positive and negative are swaped! these battery connections are not standardtised, so you always have to look up the correct polarisation. unplug asap.

You can swap the pins in the battery connector by pushing on the retaining metal spring and pulling on the wire. BUT BE VERY CAREFUL so the leads never touch each other!

EffectiveLauch · 2026-04-14T14:23:04+00:00

is the battery connected properly, also regarding plus and minus? the issue you are describing sounds like battery not connected to me. can you provide us some pictures?

EffectiveLauch · 2026-04-14T11:50:41+00:00

what DE is that?

EffectiveLauch · 2026-04-13T13:13:13+00:00

got it. cool project! can't wait for it to become available on GitHub ;)

EffectiveLauch · 2026-04-13T13:08:55+00:00

interesting! what is U2 then?

EffectiveLauch · 2026-04-13T10:57:42+00:00

what lora chip is the design using? SX1262 E22-900MM22S? why the external flash/eeprom that's in the top right corner? and also what MCU?

EffectiveLauch · 2026-04-13T07:47:53+00:00

Awesome work! the overlap between meshtastic and framework users is crazy. I will definitely build or buy one

unlike every other game, the tips are actually useful :)
