To connect to Tunerstudio over Wifi, you can use the ESP8266-01 module. These are very cheap but a simple how-to on how to make a transparant bridge with them is difficult to find. Once you know how it’s done, it’s easy though.
It’s really very ease, you just load JeeLabs ESP-link firmware and you’re good to go.
I use a programmer to load new firmware. The ESP8266 works with TTL level serial so you cannot connect it to the serial port of your computer. You need a serial to TTL converter, or a USB to TTL converter. I’mm using a USB converter as they’re very easy to use. Plug them in a USB port of your pc and simply plug the ESP8266 into its socket. Too bad these programmers don’t have buttons to Reset or Flash, so I added 2 buttons to make this to avoid soldering wires or having to use a breadboard.
I made this small adapter that sits between the programmer and the ESP module. There’s 2 buttons on it to Reset / Flash it.
Once you have connected everything according to the schematic, loading new firmware is done this way:
- press and hold the Reset button
- press and hold the Flash button
- release the Reset button
- release the Flash button
That’s it, the ESP is now in Flash mode.
Loading new firmware is done using the ESPTool.
