Arduino-esp32: ESP32 does not accept OTA

[williamesp2015]

PlatformIO 3.5.3a7
Platformio.ini
[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
upload_port = 192.168.1.6

13:50:30 [INFO]: Upload size: 599168
Sending invitation to 192.168.1.6
13:50:30 [INFO]: Waiting for device...
13:50:40 [ERROR]: No response from device
* [upload] Error 1

I have tested with:
[env:esp32dev]
platform = https://github.com/platformio/platform-espressif32.git#feature/stage
board = esp32dev
framework = arduino
upload_port = 192.168.1.6
Result: Same

upload_port = 192.168.1.6

Can be many problems.
IP address correct? Can you ping the IP address?
Is the ESP32 really connected? Can you ping the IP address?
Is the ESP32 on the same local network? Can you ping the IP address?

Are you calling ArduinoOTA.handle() frequently in your loop()? Do you have many other tasks running in your app that keeps the ESP32 too busy to response to the OTA request?

I am using the BasicOTA example and after finding local IP I try to reprogram it but I was not successfull.
Sending invitation to 192.168.1.5 . ( I got it after first time finding my Esp module IP)
I also checked pinging my router and it was ok.

try using the espota.py (or espota.exe) tool directly, with something like:

espota.py -r -i 192.168.1.5 -f YOUR-FIRMWARE.bin -d -p 3232 -a YOUR-PASSWD

it will show you more debug output

what is the IP address of the maschine you work on? is it in the same
subnet? does it also have an IP from the same router? can you ping the
ESP32 (192.168.1.5) ?

[williamesp2015]

Hi everslick . My ESP32 IP is 192.168.1.5 ( I am using static IP and I can ping both 192.168.1.5 and my router IP 192.168.1.1 using Windows ping command and also by my firmware).

[everslick]

Last idea: A personal firewall on your windows machine is blocking incoming traffic on the listening port (in this case it is 25932).

Same here, example is not working. Tried two different esp32 boards. Latest Platformio with stage platform. I can see some infos on the esp side.

Ready
IP address: 10.0.0.81
Start updating sketch
[E][WiFiClient.cpp:97] connect(): lwip_connect_r: 113
Error[2]: Connect Failed
[E][Updater.cpp:251] end(): premature end: res:0, pos:0/646688

Error[4]: End Failed

[csowada]

So, problem solved. It was the Windows 10 Firewall. I've added python to the allowed apps and it works.

[williamesp2015]

Thanks to every one. In my case [ERROR]: No response from device solved after unblock python in my antivirus.

@williamesp2015 close this issue if it's solved?

[tomtobback]

Just in case it helps anybody; on my chromebook Linux (crouton chroot) i had to add a host port in /etc/rc.local to allow incoming traffic.
However, using the Arduino IDE, espota.py assigns a random host port. From the command line, i can run espota.py, specifying the host port with -P so that works. To make it work in the Arduino IDE, i edited espota.py to use a fixed port (line 266), the same as i specified in /etc/rc.local - also works well.
