  • downloaded the plugin for VisualStudio 2017 (ESP8266Wizard 1.0)
  • created a new ESP8266Firmware project with this options: Non-OS SDK, ver 2.0.0, from example IoT_Demo
  • in the property window of the project I set the COM Port to the actual port name of my TTL-USB dongle
  • hooked up my WROOM-02 as described here: http://www.espressif.com/sites/default/ ... e_en_0.pdf
  • tied IO0 to GND
  • compiled in Release mode

Here the output:

I put the oscilloscope probe on the TX line of the serial dongle and there was no activity at all.
I'm sure it works because sending chars from a terminal to the same COM port leads to see the sent bytes.

Hence, two questions:

  1. I need to configure something other in order to let VisualStudio try to download the firmware?
  2. in which document I find the settings for the WROOM-02 module? I'm talking about: SPI and flash parameters
