Flashing the ESP8266 firmware on Espruino WiFi

Thanks! Did you have any luck with the code/instructions here? http://www.espruino.com/ESP8266#use-espruino

The ESP_xxx_BLOCK size changes should only be needed if you're going to flash directly through the Espruino WiFi's STM32 - you should be able to flash the ESP8266 without having to wire up an FTDI cable - it's why I never included any pins for flashing it :)

It'll be slower, but should still be possible - and obviously a bit less messy :)

Have you actually had WiFi working properly after updating? The code you post for testing needs to wait until ready is received from AT+RST (in fact AT+RST itself may not be needed since you're just powering the module on).

Something like this should work I imagine:

    // wait for READY message
    at.cmd('', 10000, function cb(data) {
      if (data && data!="ready") return cb;
      // ask for version
      at.cmd('AT+GMR\r\n', 10000, function(data) {
            console.log(data);
      });
    });
    // power up
    digitalWrite(A13, 1);
    digitalWrite(A14, 1);
