Changing the default UART pins

Hi, I've seen in many places that you can change the UART pins to any other available pin with practically no restriction (apart from being output capability for TX), but I would like to know if there is any issue with the performance of it. For example, I'm working with WROVER-B, is the same if I s...

Can't program ESP-WROVER-B: Invalid head of packet

Hi, I was working with a custom PCB with a ESP-WROVER module with no problem. I was able to upload many projects in it, but suddenly it started saying this: Toolchain path: /home/pablo/.espressif/tools/xtensa-esp32-elf/esp-2020r1-8.2.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc Toolchain version: esp...

Re: Using all three UARTS for module communication

Were you able to find a solution to that? I'm also looking a way to use the three UART buses of the ESP32 WROVER, but I want to disable the logging from the UART0 (the USB port by default) and use that bus to connect to another device. Also I'm not looking to change the default pins, since I'm using...

Re: UART and GPIO configuration for WroverB

I liked the level shifter solution, but the problem is with the code, it doesn't let me to set the pins as outputs without panic-ing.

How can I "un-set" that panic option? I have to disconnect those pins from the flash memory even with the level shifter?

Re: UART and GPIO configuration for WroverB

So in the existing module ESP-WROVER-IB won't be possible to use the GPIO09 and GPIO10 for other purpose except flash memory, right? On the other hand, I had programmed the WROVER to work in DIO mode, so those pin should have been available to use but I got the "IllegalInstruction" error. What else ...

Re: UART and GPIO configuration for WroverB

I'm having a similar problem, but the thing is that I configured the sdkconfig as DIO mode for the Flash memory. so that should leave GPIO09 and GPIO10 free and being able to use them as UART1 (on their default configuration) or just some extra Input/Output pins, right? Because my program crashes ev...

Re: CMake, custom components and Windows

Can you give me an example of your CMake files? because i can't add the esp32 components folder which hold the IDF libraries, and using absolute path for every component in every files is not code friendly (at least for me).

Best regards.

CMake, custom components and Windows

Hi, I used to work with the IDF under Linux distro, but due to external forces I have to change to Windows. My problem is that is not even similar to use the IDF under linux, so I can't make it work. After installing the toolchain, and following the installation guide (and some video tutorial) I sho...

Re: PCB manufacturing and assembly

I used PCBWay and they soldered an ESP-WROVER-IB, I don't know why they wouldn't solder the ESP-WROOM-32 module. I guess what's important is to find some supplier with the module you need and add the part number (or link) to your BOM list. Here is a link to a supplier: https://uy.mouser.com/ProductD...
