ESP-14 Flashing

Postby slaff » Thu Oct 29, 2015 8:53 pm

There is a new ESP chip that has integrated low-energy STMicro STM8S003 MCU named ESP-14. The idea of having these two MCUs sounds good to me. What I still do not know is if there is a way to program the ESP MCU? Can we set from STM8 the ESP in flash mode? Can we send the new firmware to the ESP via the STM8 MCU?
I am using the ESPs not only for WIFI but also as SmarConfig device, MQTT + SSL client, CaptiveProtal with WebServer and that does not come by default with the AT firmware which is in ESP-14.

If I am able to do this, even at the cost of having to learn another SDK and buy another flasher (STM8 one), that will be great. But is this the case?

Dear Sir,

ESP-14 module is from Ai-thinker company not us.

M_PD5 and M_PD6 are the UART interface. E_GPIO0 is the boot mode select pin.

If you need to reprogram the flash on the module, you can use above uart interface and configture GPIO0 to be low voltage.

Please try again.

More informations, you can refer to http://www.ai-thinker.com.

Thanks.
