Re: Example of using YModem protocol on ESP32

Thanks for the example , Requirement in one of my project is to flash from host silicon by supplied ".bin" instead of esptool.py or ESPFlashDownloader utility. I can understand that ESP32 needs to be put in to download mode with required GPIOs like - EN pin ("enable") pin was low and is pulled high....

Re: Flash through host and Esptool

Thanks both, @kolban : I was specifically looking for c# as Compact Framework does not support any form of python. @f.h-f.s.: The requirement is non-ota method as fail-safe method if esp has issues with connection to router or vice-versa. This is in accordance with existing solution for other flashi...

Re: ESP32-DevKitC issue with esp-at (AT firmware)

This seems to be fixed by latest firmware with AT routed on UART0 (same as debug) and sending CR+LF on enter of the command.
Thanks.

Re: ESP32-DevKitC issue with esp-at (AT firmware)

Thanks ESP_igrr, I tried with redirecting AT output to UART0 , but since both redirect to same COM , AT commands were not working after seeing Ready. Hence needed seperate COM with UART1 and GPIO RX16 and TX17 as output , but still then not seeing any activity on UART1. There is similar post on the ...

Re: ESP32-DevKitC issue with esp-at (AT firmware)

Update about issue : Repeated warnings when converter is plugged in to PC is now resolved by changing interface seems. But main issue still persists (hang?) . Also , it seems can't use updated esp-idf in the esp-at firmware since it is tied to particular checkin. Could it be the issue? If esp-idf is...
