Hey Daniel! I just have a basic question here... Could you please send me an image of your circuit? The one you suggested hasn't quite worked for me :/ Thank you :)

danielweidman commented 1 year ago

Hi there! I can send an image later. For now though, can you let me know if you are using a premade IR module (like this: https://www.amazon.com/Dorhea-Transmitter-Sensor-Electronic-Building/dp/B08X2P7P11/) or a raw IR led and resistor and/or transistor? Also, what microcontroller?

jacojaco12 commented 1 year ago

Hey! Thanks for being so attentive :) I'm indeed using a premade IR module. As for the microcontroller, im using an ESP-WROOM-32.

danielweidman commented 1 year ago

Cool! (and no problem).

Here is basically what I have for my ESP32:

Does that match yours?

IIUC, it's maybe not considered best practice to use VIN for the 5V supply as I do, but since it's connected by USB that pin will provide 5V out. You could alternatively connect the VCC/5V pin on the IR module to the 3V3 pin on the ESP32 board, but it might make the IR signal weaker.

Jesus, it finally turned on. However, both Pixmobs seem unresponsive. I'm certain it's not their batteries, as I opened one of them just to check if they were still alive, which they in fact are. It isn't the IR Led either, as I can see it turned on with my VR. Any ideas on what might be causing this?

danielweidman commented 1 year ago

What if you try removing and reinserting the batteries while sending IR commands quickly?

Hi Daniel! I am using an Arduino Uno and a premade IR module for my pixmob bracelet. Can you send me a quick schematic for your circuit? This is my first project EVER because my bracelet didn't receive the stay on code at the end of the Eras Tour and I desperately just want it to turn on (nothing fancy). I am a 43 year old veterinarian and mom and am at bare basics. 🥴

@Vetmom79 and I figured this out on Discord! The issue was that sometimes WAIT_BEFORE_SEND needs to be set to True in config.py. I've just updated it to be True by default.
