How to use ESP-AT with ESP32P4 as host and ESP32C6 as controller?
Posted: Tue Sep 02, 2025 1:02 pm
I have a development board that has ESP32P4 chip that is connected to ESP32C6 module over SDIO pins.
I have prepared the development environment with installing required software such as IDF and AT
But, how can I flash the C6 with AT firmware? I know that there is
If I flash at_sdio_host to ESP32P4, can I flash the AT firmware to C6 module? or I need some SDIO firmware preinstalled on C6?
I am bit confused.!
