WIFI bootloader install

Recommended Posts

I am trying to set up the WIFI with my V4 board (Nucleo controller).

I have loaded the nucleo_esp_loader.bin  firmware the same way I load the normal  PIN2DMD software using the ST Link Utility and the USB port on the Nucleo that is on the small breakout board.

The blue status LED on the Nucleo is on.

I then move the USB cable to the User USB port on the Nucleo and run  ESP8266Flasher.exe.

I already have the St virtual port drivers loaded and everything looks good in Device Maanager.  

When I try to flash the ESP8266 I get an error:

Note:Begin find ESP8266.
Note:ESP8266 ACK success.
Note:ESP8266 ACK success.
Error:Read ESP8266 register timeout.
Note:ESP8266 ACK success.
 

Any idea where I am going wrong?

 

Regards

Steve

The ESP8266Flasher.exe is very timing critical which may cause problems on some PCs.

Best is to flash the esp with a usb serial dongle directly attached to the ESP

Thanks Lucky,

Is there some info about how to connect the 232 to the ESP? I don't understand the direct connection part. The ESP I have is a surface mount part that is soldered to the V4 board.

Do I connect to the RS232 pins on the V4 board?

I tried again with the on board USB and it worked this time. Wifi is all set up and connected to my home WIFI router. 

How do I use PIN2DMD.EXE over WIFI?

How about PIN2DMD editor?  there is a place in configurtion to enter the address, I guess this is just the IP address eg 192.168.1.118 . it mentions port 9191 but i expect I don't need to enter this. In any case I could not get the editor to connect over WIFI.

pin2dmd.exe /ip 192.168.1.118 should work. In the editor configuration you can also edit the ip address. To be honest this has never been extensively tested and today the esp is only populated for go-dmd usage. USB connection is still recommended for pin2dmd.
