- Sat Nov 02, 2019 3:18 am #84394 I uploaded OTA program info my Nodemcu from laptop. Now I can reprogram the nodemcu module through wifi hotspot.
Now I wanted to know how can I reprogram it with my android phone instead to laptop?

https://arduino-esp8266.readthedocs.io/ ... eadme.html describes the 3 different ways OTA is commonly used.

If you mean the Arduino IDE OTA instead of serial connection then that may be quite challenging. You would first need to have Arduino IDE on Android and then the means to add on the OTA support. I am not sure whether that has been done yet.

If you mean OTA via a browser then that should work fine as the sending device needs to just have a decent browser and the bin file to update with. The latter could either be produced on your normal IDE or possibly the Android Arduino could do that.

The third method is for devices to self OTA update from a web server.
