ESP32 Hosted

ESP32 Hosted (ESP-Hosted-MCU) is a solution that allows you to use ESP32 modules as communication co-processors. This solution provides wireless connectivity (Wi-Fi and Bluetooth) to the host module, enabling it to communicate with other devices.

Configuration variables

• variant (Required, string): The variant of the ESP32 co-processor that is used by the host. One of ESP32, ESP32S2, ESP32S3, ESP32C2, ESP32C3 and ESP32C6.

• clk_pin (Required, Pin): The SDIO clock pin.

• cmd_pin (Required, Pin): The SDIO command pin.

• d0_pin (Required, Pin): The SDIO d0 pin.

• d1_pin (Required, Pin): The SDIO d1 pin.

• d2_pin (Required, Pin): The SDIO d2 pin.

• d3_pin (Required, Pin): The SDIO d3 pin.

• slot (Optional, int): The SDIO slot number. Defaults to 1.

• reset_pin (Required, Pin): The reset pin of the co-processor.

• active_high (Required, boolean): If enabled, the co-processor is active when reset is high. If disabled, the co-processor is active when reset is low.
