kbaud: Can you explain why you would need those extra pins? Maybe we could provide an alternative solution.

I can test this during the weekend, I have an unshielded module, that I can use. Fingers crossed.

Hi martinB, The wheel is already invented. It's called OTA server polling. Your mobile phones do that actually, by looking for updates themselves. Since all servers can be different, with sever thousand different authentication processes, there is no stantard example for them. The provided OTA examp...

I have just 2 things to add: The next revision should use the PICO-D4, which is a 7x7mm size package, with dual core ESP, 4MB flash and crystal inside, also with matching components for 50ohm transmission line. With that one you can basically put a PICO on your module wire our the GPIO pins to the b...

IS there anything else on the board that can be powered up while you are trying this? Also the breadboard is not so power efficient, and a good quality USB cable is required. I hade the same issue before, then I swapped the USB cable, and problem gone. I always used the one of the Devkit boards, not...

Illuscius: Does your driver sends a Write enable command to the Flash?

hgptamn: If you can read, you should read out the registers and check for write enable and write protection bits, so you can make sure the flash can be written.

Check our this thread.
This works only with ESP-IDF.

It's worth posting this write issue into under the thread here on the forum, or on Github, to see if he can help you out. I haven't tried that myselft just browsed the code, what it contains. As for the SPIFFS, you don't even have to know at which offset do you store the .bin, the SPIFFS API can fin...

1 additional thing for the above: You can try to use SPIFFS on the programmer ESP32, to store the .bin file. There is an example in the ESP-IDF repo: [url]https://github.com/espressif/esp-idf/tree/master/examples/storage/spiffs[/url Using this, you can essentialy store your .bin file you want to pro...

Dear Vader Mester, Thank you for your time in replying to my query. So does it mean the factory image in esp32 doesnt have an OTA Upgrade capability and does the default image (factory image) have only factory image and no OTA Partition, Due to which we have to initially program the flash with OTA ...
