Issue Description I am using ESP32 Wroom 4MB and I am trying to upload a file to Firebase Storage from SD card. I am getting fcs callback error as "response payload read timed out due to network issue or too large data size" which looks similar to the issue #315 in Github Library https://github.com...

I got it fixed. I had schematic issue where my U6 ESD suppressor chip was not connecting the USB traces to the CP2102N chip. So I modified the boards to have proper ESD connection on pin 1 & pin 3 of my U6 chip.

I can program the board with COTS USB to UART board like this one which also has CP2102N chip so that means I have proper drivers in my PC. Only when I use it with my custom PCB I don't see any COM board.:

<r>I am using CP2102N-A02-GQFN24 on my custom PCB to program my ESP32 board. I am not able to see any COM port on my Windows 10 PC. I can connect to an off the shelf CP2102N-A02-GQFN28 USB UART bridge board to my computer. So I think that rules out driver issue then I am not really sure what else co...

I am seeing the serial printouts on my terminal window which means that the Rx & Tx lines are correctly wired and works properly. I have a SD card slot which is connected to GPIO12 which has pull up with 56K resistor on that line. I later removed that resistor to isolate the issue but I could get in...

I have a custom board where I am using an ESP32 Wroom module. I am not able to flash code via serial communication. I am using FTDI232 USB to UART for serial communication. I am able to get serial messages in my serial monitor which mean there is no issue in serial wires. I have attached a capacitor...
