No "ready" message when using SPI AT

Postby andrew_aus » Tue Sep 06, 2022 2:01 am

Hi,

I see that after the ESP-AT (UART) firmware starts up and is ready for normal operation it emits a "ready" message out the UART.

But I am using the ESP32-C3 AT SPI build, which is mostly working, but I don't seem to ever get a ready message, not after power up and not after issuing the AT+RST command.

Is this the expected behaviour, or must I be doing something wrong with my handling of the SPI protocol to not see it?

Thanks.

Yes, SPI AT does not output ready by default, you can add the code

Code: Select all

at_spi_write_data((uint8_t *) "\r\nready\r\n" , strlen("\r\nready\r\n"));
manually in here https://github.com/espressif/esp-at/blo ... ies.c#L230, and then recompile SPI AT.
