Re: ESP32 as Bluetoothg/Spotify Connect receiver

Hi Freddie, I also looked into making a Spotify Connect receiver and have a few hints for you: First this is not really outdoor friendly because the ESP would need direct internet access for Spotify Connect and therefore you need a mobile access point. This is possible with your mobile but very batt...

Re: WPA2 Enterprise connection

Unfortunately I am facing the same problem. I want my devices to connect to our corporate Wi-Fi that I don't have control over. I can connect with my Android phone with only Identity and Password (although I don't really know what android _really_ sends. Unfortunately I lack the neccessary knowledge...

Re: What would you like to see in The Next Chip?

It's not really a request but rather a feeling, not even rational. Every time I am encountering a bug there is a voice in the back of my head that fears the Xtensa core or compiler might be at fault (even as this is highly unlikely) even tough it is my own fault most of the time. Having an ARM would...

Re: Factory app update from MicroSD

If all my instructions are executed from IRAM I don't need an additional OTA partition. For the processor it does not matter if the update code that is writing the factory partition is loaded from an OTA partition or from IRAM, it will only be a problem if functions outside of IRAM are called. PS: H...

Factory app update from MicroSD

Hello, I have a hardware that has an always available MicroSD card. For updates I want to upload new binary images to the Micro SD via HTTP server (or manual copy of course). Optimally I do not want to reserve (too much, if any) memory in flash (for OTA partition). I see the following approaches to ...

Re: Problems setting up Windows Linux Subsystem with esp-idf

I have written down the overall steps I did here https://esp32.com/viewtopic.php?f=2&t=4166#p21876 but it is really important to follow each and every step, especially in the linux setup guide from Espressif. If you took the hello_world from IDF examples the Makefile contains the line: include $(IDF...

Re: MSYS2 is slow on Windows 10

For everybody on Windows 10 I can wholeheartedly recommend the Windows Subsystem for Linux (WSL). Especially as my work PC I can't make exceptions to Windows Defender. Compile time dropped from >15 minutes to <2 minutes. Also starting the flasher and monitor are a lot faster. Setup is pretty straigh...

Re: Scrambled UART data after esp_restart()

Toolchain is 20180110 and IDF was at master of January 12. This was a very good trigger, maybe it is now working because the fifo is correctly cleared: https://github.com/espressif/esp-idf/commit/f482e9e54ce83e249e46f5ee082f6ffb61431339 This fixed was one day later :lol: I have tested for 10 minutes...

Scrambled UART data after esp_restart()

I hope this was not answered somewhere else before, I have a small uart logging application that has to run for months. The code receives data from UART and writes it to MicroSD. For recovery I do a system reset in any error case, e.g. MicroSD card could not be written or mounted, UART could not be ...
