He might have a WROVER board. IIRC correctly they have two ports and one is for JTAG.

Re: COM port in make menuconfig, syntax
As shown on my screenshot, I put "COM43" there. Is it correct? I have been doing other Windows development. large com part number require \\\ in front it. Is it the case there? I do not put slashes in front. I always type it lower case. Have no idea if it's case sensitive. If you want to try anothe...

PDM sample resolution
I could write a test app, but I thought maybe asking the question would be quicker, and maybe reveal something I would overlook in a test. I'm currently sampling PDM audio at 16 bit, but find the audio at normal levels is pretty poor, especially on mics with low sensitivity (-46dB). The mic INMP621 ...

Re: How to change separator in response from http_server
Ok, but is it possible to get something like eg. var1aaavar2bbb instead var1=aaa&var2=bbb using esp_idf? I'm guessing you'll need to do that yourself because it's not something anyone else would want. Just search for every = and &, then remove them from the string. char *src = "var1=aaa&var2=bbb"; ...

Re: If I2C protected again multible access
I believe the I2C is protected by a mutex for multi-threaded access, and a semaphore should not be necessary.

Re: Trouble with i2c and i2s running simultaneously
Any chance I could ask you to post your setup and code/Sketch please? I've heard about people having problems under Arduino with the I2C. I'm using the IDF. The code belongs to my employer. And quite frankly it's a lot of code. I don't do it in a single loop. A bunch of tasks are running in my app....

Re: BMP280 I2C temperature & pressure reading issue
We tried using the BME280. I was able to get it to work with the IDF using the Bosch libs. But when we manufactured some boards the humidity reading was totally off on a bunch. And yes, I did use the library's calibration routines with the BME internal calibration data. We were using the HTU21D with...

Re: SPI receive in SPI master, byte shifting in the buffer
I can't help much, but it seems to me that if you used incrementing numbers instead of random 126/127, then you might be able to determine more precisely what data is being lost, and therefore get closer to the solution.
