OTA for host MCU using ESP-AT

[flomarkt]

I need a way to flash my host mcu which is the esp32p4 which doesnt come with wifi hardware equipped as a SoC, so I would connect the p4 to a c6 running ESP-AT. My first approach would be to host a webserver containing the elf and a wifi network using a pi. Then to connect to the wifi using AT and then aqquire the elf with AT+HTTPCGET. Is this approach even possible or does anybody know a better way?

Probably easier to use esp-hosted-mcu to make the P4 use the C6 as a 'native' WiFi interface. After that, you can simply use the standard ota flow.

AT+HTTPCGET can make it, you can refer to https://docs.espressif.com/projects/esp ... mples.html

no sure if it's the best way.
