Re: ESP32 is the worst microcontroller I played with

Hi, I think you should post a few issues and seek help if you have problems. I'm sure there are solutions for most of the problems you are having. I also think Espressif will welcome feedback from people who push their devices to the limit, so they can learn and imporve the software that goes along ...

Hi,

Thank you for your reply. It was very helpful to detect and solve the problem.
Long story short, I use an external power supply and the magic happened.
I will buy another bunch of USB cables.
I'm glad it worked out for you :)

Re: 32kHz oscillator on ESP-WROVER-KIT-VE not working

Hello, yes, the 0ohm resistors between crystal and module pins are present yes. I've set external crystal in the menuconfig You should also make a continuity check from the pins on the wrover module to the pads of the crystal. This will check if everything is soldered correctly and the 0ohm chip re...

Re: ESP32 Wrover Cannot Flash Firmware Need Help

I don't see any issue with the schematic at first glance, only that D0 should have a Pull-Up? If you look at https://dl.espressif.com/dl/schematics/ESP-WROVER-KIT_SCH-2.pdf , bottom right corner of the PDF, you can see that every signal on the SD-Card connector have pull-ups, even data lines as well...

Re: BluetoothSerial's .println() is altering hardware timer interrupt on other core

The BT task and interrupts run at core 0 by default, if memory serves. This happens even if you print to BT on the other core. Presumably the BT interrupts pre-empt your timer interrupt. But, I checked within the interrupt which core it runs on via xPortGetCoreID(), and it runs on the core in which...

Do you know if uFL connector versions will come from these modules as well? the mini serie contains mini-1 (PCB Ant) and mini-1U (IPEX), also final S3 series there will been MINI module and from hearing - WROOM module - not hearing - WROVER module - I just did a pin-map of the WROVER-like module on...

Re: I couldnt upload code. it stucks at %6 and give timeout error.

Hi, It doesn't fail at the same stage, so my guess is that either there is interference on the UART signal lines, or you have power supply issues and either your converter or the ESP module itself resets. This can happen when the supply voltage is not high enough, or you have poor supply filtering o...

Re: ReWrite BLK3 ADC TP calibration values esp32 eFuse?

Hi, eFuse can not be rewritten. It is only possible to write it once (hence the name). You could change bit in the eFuse that are 0, to 1, but not the other way. For details, I suggest you read this: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/adc.html#adc-c...
