Re: App Issues on Android Xiaomi miA3: Selecting WiFi network not possible
I understand but then if there was no Bluetooth then the App should never arrive to the point of asking for the WiFi credentials, to just show an empty select network. It should simply stop with error I can find device or similar.

Generating a QR code
I would like in the future that RainMaker provides a callback to render a QR Code for any Firmware. Wanted to ask if someone already did it, I remember reading something about this here and I've searched for QR code in this forum but I cannot find it. What I want to do is this: Catch app_wifi: Provi...

Re: Future nice-to-have list for ESP-RainMaker
Not sure how this is any different than the current text field for "Name" parameter. Text field is actually the default if you have not specified the UI type. Can you elaborate? Interesting, I never see that, so this is already possible? Can someone point me to the right example? I just want to be ...

Re: HTTPS issues on IDF 4.2 / 4.4 (tried both)
Thanks WiFive I searched and found a github issue pointing to this (old 2008) : menuconfig -> Component config -> ESP32-specific -> Main task stack size But it's not there. Only thing found is Use fixed static RAM size that looks like another thing. Can you point me what is the route to find this in...

Thanks Piyush, I think we know what's going on after looking at the serial: CalEPD component version 1.0.6 Wave5i7Color() constructor injects IO and extends Adafruit_GFX(600,448) [0;32mI (935) cpu_start: Starting scheduler on PRO CPU.

Re: SPI Master
I second Victoria recommendation here. I would also like to mention, that many SPI peripherals, need a reset before starting communication.
I checked the ra8875 in LVGL and has one, a part of a memory clear, maybe that's something you need to do additionally before sending your SPI commands.

[Solved] App Issues on Android Xiaomi miA3: Selecting WiFi network not possible
Hello RainMaker team, I must report that also with Android I'm having problems with some devices. Clients report to me that they can scan successfully the QR but when they try to send the WiFi credentials they get stuck in this screen https://pbs.twimg.com/media/E9VuXmdXoAAnFmX?format=jpg&name=large...

Re: Stepper Motor speed increases on its own
Looks like a very hairy issue. But can't you add some output parameters via Serial and leave it connected, just to see if you can detect what is changing automatically? Since it's a component port that comes from Arduino, the part that calls my attention is that they are using esp_timer_get_time() i...
