Also just for prototype, take a look at sentrius gateway (not exactly something you may need), this has multiple wireless access, such as Wi-Fi, BLE and LoRa and LTE too https://www.lairdconnect.com/iot-devices/lorawan-iot-devices/sentrius-rg1xx-lorawan-gateway-wi-fi-ethernet-optional-lte-us-only

InsightMike•3/4/24, 2:37 PM

You shouldn't have any compatibility issues. Most important is selecting the right frequency for your region. If your gateway is just used as a "packet forwarder" for low volume traffic, any will work fine. If you need to embed your LoRaWAN Network Server on the gateway then you'll need a higher end product. Also, some gateways have better range performance and better high traffic performance, but if you're just doing some small system testing that won't be an issue.

Wow, the gamut of disciplines. @Navadeep will be a friend.

Happy to have you aboard. If you have any suggestions/requests let us know in the #suggestion-box or just throw them in here. Also we have weekly events right now that we're going to increase in frequency soon and you're more than welcome to attend those as well.

Hey guys, IDE poll just ended. No real surprises here: https://discord.com/channels/1130679493799977062/1199293807737450538/1214147961366249482. VSCode dominates, followed by Eclipse, Arduino IDE, and STM32. Anyone shocked by that?

I have another poll that's tech-adjacent. Since we're going to be opening up to the world soon, we'd like to know where do you guys get your engineering information/education? I'll post a poll on that soon.

Budweiser•3/4/24, 3:00 PM

I strongly condemn the use of http://www.libgen.is where people type in e.g. the title of a book or a general search term relating to book titles and http://sci-hub.hkvisa.net where people e.g. type in a papers DOI, these are grave copyright violations!

BenCos18•3/4/24, 6:05 PM

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

UUmesh Lokhande Yes, the subscriber sends back a response message to publisher

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 Lokhande•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

techielew•3/4/24, 11:43 PM

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.
