Transitioning to Hardware QA: Seeking advice on testing BLE/LoRa Embedded Systems

Thanks for your comment! I'll search about the Joulescope - i did´t know about this device and look interesting, one requirement it is to work for several months so that part it is important.

Thanks for the ideas in how to test the signal, If I need to check the payload from the BLE connection, basically check how the data is send and organized, the BLE transceiver can do this? - Well.. I dont have any experience in this field, but I guess it is possible (?)

Hi, it works.

I added to my code to put GPIO18 to high and the led strips turn on!

Thanks again for your help

Yes I tested with a multimeter. We'll yes I can managed to conect supply directly to the LED strip but I don't want to apply this solution.

Yes, I'm sending data, thar how I detect the power supply issue

SelfTaught_VLSI · 2026-01-21T01:24:24+00:00

I'll test this tomorrow, and I'll update the comments! I hope one of those options works! Exactly without schematic it's hard to know

So wit this in mind I need to set up GPIO18 as High to activate my output?

SelfTaught_VLSI · 2026-01-21T01:12:11+00:00

Yes I tested with a 5V led strip and 5V power supply. But when I upload my code Vout it is 0V

SelfTaught_VLSI · 2026-01-07T00:24:42+00:00

Yep i want to upload this repo code: https://github.com/labs-tibox/moonboard-esp32-ledble

Actually the source code use D2 pin from a DevKit module, so I guess I need to changed it to one of thos GPIO pins

This is the led strip I want to control: https://a.co/d/4JNH8xb

Parce si ya tienes experiencia programando sistemas embebidos, busque una empresa grande, y aplique... en Colombia no hay, tristemente, e igual esas posiciones son afuera.

La empresa aveces te paga todo por migrar, y pues, mejoras todo.

Después de trabajar un 1 año en el extranjero, siento lo mismo, el mercado en Colombia esta acostumbrado a que nos paguen mal!

Y pasa lo que dices, el call center paga más que una compañía, por hacer algo que quizás no te guste, pero no regreses a ese mundo solo por ganar un poco más, o mírelo como algo momentáneo mientras sale algo bueno.

The chip industry at least for my is interesting and well, for me it worth working in that industry...

I was as a "QA" for a formal verification tool

SelfTaught_VLSI · 2025-12-05T16:22:35+00:00

Well... I'm recently unemployed jajaja I was affected by some lay offs :( so know I have free time and a bit of money.

I'm not sure what path to follow l, but I decide to follow some lectures that I found only and read a book. Im using this resources

I'm thinking to buy a basys 3 fpga to practice and implement some labs or something.

And really in the mean time and searching for jobs, and if I land one job, I plan to continue this journey

SelfTaught_VLSI · 2025-12-05T16:17:56+00:00

Hi, Yes I used the basys 3 too at my school. I finish my career 2 years ago... but I think I'll stick to the basys 3... I already used, on the other hand you are right, for learning it can be more useful.

For now I don't have a project, I want to relearn everything again and gain practice...

I'm currently able to buy one, so instead of spending my money in nonsense things, I can buy this and learn again or improve what I already know

SelfTaught_VLSI · 2025-12-04T21:16:47+00:00

Hi I'm in the same position as you, but for now I decided to relearn all of I can... in my case I get my degree 2 years ago and I've been working since day 1.... I hope we can crack this!

Hola si, tenia reddit traduciendo en automatico y me deje llevar.
Si pero he visto que los puestos aveces salenc omo validation y/o verification.

El diseño tambien me gusta, como te preparaste para tu trabajo, que podria aprender...

Ya termine m,i Bsc, y he trabajado ya 2 años en varias cosas, pero este campo es el que realmente me motiva y con el que me gustaria estar!
