- Sun May 01, 2016 7:07 pm #46649 Hi, I did all setup to get OTA working. ESP8266 connected with IP 192.168.1.140
I installed python 2.7
But when try to upload I get java error cannot find python.exe
There is no option for OTA in tools why?

SOLVEDD: Forget to select option on python instalation path to python.exe

I have to send again ota sketch to module than upload new sketch after that can't upload no more. Haave to upload again OTA basic via COM
How can I upload more sketchs via OTA without get "NO ANSWER"?

I assume you have OTA routines included in your sketch previously successfully loaded using OTA (using BasicOTA.ino as an example).

If you have NO ANSWER on second OTA upland, I would check if either of the following works:

• Manually reset module, check in Serial Monitor if module's IP is there and try OTA upload again
• Completely erase flash in module – ref. https://github.com/esp8266/Arduino/issu ... t-96399149 and redo the whole OTA procedure starting with serial upload.
