ESP-AT with SPI cant handle very fast incoming data
Hello, I am using ESP32 with ESP-AT library in SPI mode. ESP32 is connected to MQTT Broker which publishes the data very fast at one specific topic which shows list of users online. its publish data every 100-200 ms thus most of time ESP32 skips few Important responses on other topics from server an...

Re: Cant Compile project with component in Linux environment
so as you asked if component directory contains lowercase letter it actually wasn't it was like ''Components" when i renamed it to "component" finally idf was looking into components directory and i could compile the program successfully. Thanks for pointing that out.

Re: Cant Compile project with component in Linux environment
What i also found that when i build project it looks like ESP-IDF not even looking at CMakeLists.txt in each component because when i add invalid source file name there as far as i know esp-idf should return that no .c .h .cpp etc file found.

Error while Uploading firmware to PCB : Invalid head of packet (0x78)
We have ESP32 on Custom PCB Board. when it is powered up from Mains Supply of 230v/3.3v and Connect programming Header to PC to flash the firmware it fails with A fatal error occurred: Invalid head of packet (0x78) very frequently. Can someone please explain what can cause this error? Programming he...

Re: unusual voltages at GPIO6 to GPIO 11 Pins
After changing the code yesterday, the behaviour of the out is altered so max voltage is bit different but its still more than 3.3v. the way I measure is to set the GND to the MCU GND pin and place the probe right on the pin where I want to measure.
and here is zoomed in waveform :

Re: High Voltage Ripple across ESP32
yea it makes sense now. i totally missed the EMI noise due to converters probably the Oscilloscope picking up some of that by providing power from pc tells basically nothing

Re: unusual voltages at GPIO6 to GPIO 11 Pins
I am measuring this with Oscilloscope. and yes i am aware of this pins carries the AC'ish waveform. but since this is Digital 3v3 LVCMOS Standard Line I expected to see the switching value between 0v-3.3v but in reality the it goes upto 4.14v max as it is seen in picture below. The development board...
