Problem with ESP32 OTA

Hi
After upgrading to the latest Visual Micro, i start to get an annoing error when trying to use OTA to update the firmware.

The error is:
Code
Select All
espota.exe: error: option -p: invalid integer value: '{network.port}'


And the command that is called looks like this:
Code
Select All
espressif\esp32\tools\espota.exe -i "192.168.1.38" -p "{network.port}" "--auth=" -f  "firmware.ino.bin"


Updating through the serial port works fine.

Thomas

Hi,

I don't think this is related to update but lets explore.

The {network.port} has not been resolved.

It can be resolved one of two ways

1) You have apple bonjour for windows installed and the IP address automatically appeared in the serial/ip ports list. You selected the IP address from that list. You DID NOT enter the IP address manually at anytime.

2) You have a board.txt file in the local project folder that specifies the network.port= property. The network.port= property usually defaults to 8266 but is set in your code.

Which method are you using to resolve IP and port?

To confirm that you either need a board.txt in the project to specify the mDNS port or have apple bonjour installed so the IP address and board name appear in the ports list.

Seeing the following means the port is not set. Normally 3232 for esp32 but check your code.
{network.port}

Hi

Sorry for the delay. I destoyed the voltage regulator on ESP32 board, and I have not had the time to repair it..

Anyways, I'm selecting the IP in the dropdown box, and I have ESPmDNS.h in my code. 
At the moment I can't remember if I had bonjour installed at the time.

If you Ip you select from the list is just an IP without board name or chip id next to it then you are not using bonjour

Make sure you have set the network.port=8266 in board.txt

This is unrelated to the upgrade

Thanks
