Yep
As long as you use the right frequency he gateway itself is pretty reliable

wafa_ath•3/4/24, 6:56 PM

Do you know how to do it?!

boualleg sabrina•3/4/24, 7:15 PM

guys, have you worked with stm 32, nucleo-64, development board ?

Wwafa_ath Do you know how to do it?!

Umesh LokhandeOP•3/4/24, 7:19 PM

I'd suggest download python scripts from online sources like ChatGPT for publisher and subscriber and evaluate the feature. I never needed to implement. As it comes as a feature of MQTTv5

Hi all! My name ist Flo, 29 from Germany. Studied computer science and have been working as an embedded software developer for one year now. Mainly Yocto, RTOS, C/++, Python, ARM. I'm here to help where possible and LEARN. Also I'd really enjoy some funny, relaxed tech talks, as I sadyl cant do that IRL. :D

Welcom @Flo We're happy to have you here! lol I'm not sure whether I can have funny, relaxed tech talks irl but I try every Friday!

What are you looking to learn now?

Flo•3/5/24, 9:20 AM

At the moment I am trying to build an armbian image for a very old and unknown tablet namely "Prestigio PMP5197DULTRA". It has an Allwinner A10. Sadly it does not use device tree files but fex files. So that's the problem right now. Also I never built/customized a Linux image from scratch. If anyone has some hints for me, they are greatly appreciated!

Flo•3/5/24, 9:22 AM

Thats what im practically learning at the moment and besides that im watching DevCon talks on YT and reading some eBooks. Also need to learn more about Yocto, RTOS and C++.

Hi @Navadeep ,
Thanks for the compliments on the article about Return Currents.

kristof-at-embeetle•3/5/24, 5:26 PM

I've noticed some people had issues accessing the article on Medium, hitting the Medium login wall.

Nice. You've used? Which RTOS for which micro? And what are some of the common challenges you think we should address?

Aditya thakekar•3/6/24, 6:11 PM

ESP-IDF has both features so we don't have to separely use free rtos.

Aditya thakekar•3/6/24, 6:12 PM
