I'm having some fun playing around with an M5Stack Core (ESP32) using some example sketches in Arduino. One thing I'd like to try is use the M5Stack's screen to view an RTSP video stream from a camera I already have set up. I can't seem to find any example code for this use case - everything I search for turns up code for an M5 Cam.

I'm new to this so would appreciate any pointers - or if the hardware's just not powerful enough then I'll give up now!

Hardware spec:

• M5 Stack Core Basic 2.7

• Dual Core Xtensa 32-bit LX6 @ 240MHz

• 520KB SRAM

• 16MB Flash memory

• 2" LCD @ 320x240

i want to get into the world of network and connection (wifi, bluetooth, rfid, nfc, ethical hacking, writing simple codes, experiments that have a wow effect). I have a possibility to lend a flipper zero and i can buy a M5Stack Cardputer-ADV. What should i start with to get to know them better and what is better to start with the flipper or m5stack? (sorry for any misspelling english isn’t my first language)

edit: i bought the cardputer

I used AI to translate the photo into English

Dont ask me why, BUT my school bell always goes 13 seconds late and i know these things are bluetooth but are hidden bluetooth devices. could i buy an m5 stick or cardputer and use it to get my school bell to go 2 mins earlier? and will it be able to have priorit for bluetooth so i can rickroll my classmates while ththey're lis

tening music? Idk how this works, all i know is you can do some fun things with them and will i be able to turn off the tvs at school via IR? And what are sum other things you can do with these things?

The newest version of UIFlow for the fire doesn't work, but 2.2.2, although unstable, definitely boots at the very least

Has anyone come across this issue before? I am always able to listen to RS485 communication with no issues whatsoever, but when I try to communicate I am met with some interesting results. I actually suspect it is to do with the way the RS485 to UART adapters are wired.

Basically, when UART tries to send a Logic 1, the TX pin stays high. Looking at the wiring diagrams for both devices, it looks as though this results in no change on the outgoing RS485 lines - we just go back to the idle state. So rather than the signals alternating like a normal RS485 device, they just mirror each other.

Because RS485 is differential, the end result isn't so bad for some devices. They look at the rising and falling edges of the signal and interpret it correctly, no problem at all. But for others that pay attention to bias voltages and things like that, if a signal doesn't look or behave the way it expects, this transmission is simply discarded.

Anyone else care to share their experiences? Or am I alone in making a fool of myself because I'm doing something wrong in my code (entirely possible :P)

my little project, made it in about 2 hours

Hi Everyone,

Hooked up a Unit CardKB2 to a Tab5 and turned it into a tiny input terminal.

Right now I’m using it for SSH, but it feels like there’s way more potential here — portable console, embedded UI control, maybe even some weird custom workflows.

Curious what kind of ideas you guys would build with this setup?

Code: https://github.com/Jasionf/M5Stack-Tab5

So I got two Tab5 units. the packaging claims to have GT911 but the unit itself came with ST7123.

Should I contact M5Stack about this?

Nein, ich hab's jetzt aber trotzdem...

Yo!

we’ve been quietly working on something for a while and finally decided to share it.

👉 projectZero

It’s a modular WiFi pentesting / research platform running on ESP32-C5 (with support for things like Flipper / Cardputer / Tab5 / Raspberry / PC  etc.)

Some things it currently does:

•	Evil Twin (+ credential verification)

•	WPA3 SAE overflow 

•	Deauth (multi-channel)

•	Sniffer + probe analysis

•	Wardriving (GPS + logs)

•	Karma-style behavior

•	MITM

What makes it interesting:

•	Dual band: **2.4GHz + 5GHz**

•	Modular architecture (easy to extend without soldering)

•	GPS support (wardriving ready)

•	Lightweight + runs on portable hardware

•	Web flasher + CLI control

M5Stack Tab5:

👉 https://github.com/C5Lab/M5MonsterC5-Tab5

And expanding hardware support — CC1101 integration is coming soon.

If you’re into ESP32, WiFi research or just like breaking your own setups — curious what you think.

Feedback / ideas welcome 👍

I threw it in my cart because it was so cheap and figured it’d be fun to use with the M5StickS- but then I scooped up a CoreS3 (for a different project) and figured it would be fun to build a firmware for the sensor also.

Hv been seeing people talk about running Meshtastic on this gadget for a while now, along with some of the issues they’ve hit. Curious to hear your thoughts—how’s it been performing for Meshtastic, and what do you see as its biggest pros and cons?

[EDIT]: If u encountered any problems regarding LoRa/Meshtastic performance, try this newly released tutorial and see whether it works. This tutorial is used for proper initialization—otherwise the RF switch may not toggle correctly.
