### Application Example
|
||||
|
||||
Currently there are two software configurations that support OTA updates.
|
||||
|
||||
- [Classic OTA](#classic-ota-configuration): Arduino IDE 1.6.5 and 1.6.5-947-g39819f0 (of July 23, 2015) version of ESP8266 board support platform package that provides first OTA implementation, yet without support for [ArduinoOTA](https://github.com/esp8266/Arduino/tree/master/libraries/ArduinoOTA) library. This particular configuration soon will be depreciated in favor of new implementation described below.
|
||||
|
||||
- [ArduinoOTA](#arduinoota-configuration): Arduino IDE 1.6.7 and 2.0.0 version of platform package. Arduino IDE 1.6.7 is the first release that provides support for [ArduinoOTA](https://github.com/esp8266/Arduino/tree/master/libraries/ArduinoOTA) library.
|
||||
|
||||
For information how to install ESP8266 board support in Arduino IDE please refer to https://github.com/esp8266/Arduino#installing-with-boards-manager. Once installed, it is possible to switch between available versions of platform package using Boards Manager:
|
||||
|
||||
|
||||
|
||||
Instructions below demonstrate how to configure both [Classic OTA](#classic-ota-configuration) and [ArduinoOTA](#arduinoota-configuration) using NodeMCU 1.0 (ESP-12E Module) board. You can use other boards assuming that they meet [requirements](#basic-requirements) described above.
|
||||
|
||||
|
||||
#### Classic OTA
|
||||
Instructions below demonstrate configuration of OTA on NodeMCU 1.0 (ESP-12E Module) board. You can use any other board assuming that it meets [requirements](#basic-requirements) described above. Screen captures have been made on Windows 7 and this instruction is valid for all operating systems supported by Arduino IDE. Differnces are minor like for instance name of serial port on Linux and MacOS.
|
||||
|
||||
1. Before you begin, please make sure that you have the following installed:
|
||||
- Arduino IDE 1.6.5 and 1.6.5-947-g39819f0 version of platform package,
|
||||
- [Python](https://www.python.org/) 2.7 (do not install Python 3.5 that is not supported).
|
||||
|
||||
2. Now prepare the sketch and configuration for the upload over a serial port.
|
||||
- Start Arduino IDE and load sketch DNS_SD_Arduino_OTA.ino available under File > Examples > ESP8266mDNS
|
||||
|
||||
|
||||
**Note:** This sketch is available only for 1.6.5-947-g39819f0 (of July 23, 2015) platform package. It was removed in [#980](https://github.com/esp8266/Arduino/pull/980) from GitHub repository.
|
||||
- Update SSID and password in the sketch so the module can join your Wi-Fi network
|
||||
|
||||
|
||||
- Configure upload parameters as below (you may need to adjust configuration if you are using a different module):
|
||||
|
||||
|
||||
3. Upload the sketch (Ctrl+U). Once done, open Serial Monitor (Ctrl+Shift+M) and check if module has joined your Wi-Fi network.
|
||||
|
||||
|
||||
|
||||
4. Only if module is connected to network, after a couple of seconds, the esp8266-ota port will show up in Arduino IDE:
|
||||
|
||||
|
||||
|
||||
5. Now get ready for your first OTA upload by changing configuration settings as follows:
|
||||
|
||||
|
||||
|
||||
**Note:** If you do not see “Upload Using: OTA” option available for “NodeMCU 1.0 (ESP-12E Module)” board, please upload the latest [boards.txt](https://github.com/esp8266/Arduino/blob/master/boards.txt) file from GitHub repository, replace existing file and restart Arduino IDE.
|
||||
|
||||
6. If you have successfully completed all the above steps, you can upload (Ctrl+U) the same (or any other) sketch over OTA:
|
||||
|
||||
|
||||
|
||||
**Note:** To be able to upload your sketch over and over again using OTA, you need to embed OTA routines inside. Please use DNS_SD_Arduino_OTA.ino as an example.
|
||||
|
||||
In case of issues please refer to information provided in section [Troubleshooting](#troubleshooting). Successful OTA process looks like below on serial terminal:
