5959
|*Location*|Your bot can receive location data, either from a single location data point or live location data. |Check the example.| [Location](https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot/tree/master/examples/ESP8266/Location/Location.ino)|
6060
|*Channel Post*|Reads posts from channels. |Check the example.| [ChannelPost](https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot/tree/master/examples/ESP8266/ChannelPost/ChannelPost.ino)|
6161
|*Long Poll*|Set how long the bot will wait checking for a new message before returning now messages. <br><br> This will decrease the amount of requests and data used by the bot, but it will tie up the arduino while it waits for messages |`bot.longPoll = 60;` <br><br> Where 60 is the amount of seconds it should wait | [LongPoll](https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot/tree/master/examples/ESP8266/LongPoll/LongPoll.ino)|
62+
|*Update Firmware and SPIFFS*|You can update firmware and spiffs area through send files as a normal file with a specific caption. |`update firmware` <br>or<br>`update spiffs`<br> These are captions for example. | [telegramOTA](https://github.com/solcer/Universal-Arduino-Telegram-Bot/blob/master/examples/ESP32/telegramOTA/telegramOTA.ino)|```
63+
|*Set bot's commands*|You can set bot commands programmatically from your code. The commands will be shown in a special place in the text input area| ```bot.setMyCommands("[{\"command\":\"help\", \"description\":\"get help\"},{\"command\":\"start\",\"description\":\"start conversation\"}]");```. See examples| [SetMyCommands](examples/ESP8266/SetMyCommands/SetMyCommands.ino)|
