Send and View data via bluetooth from esp32 to android mobile phone.

[Nespressif]

Hi all, I'm doing a project that generates some data related to the system timers, in short I show uint_64 accompanied with some string. That is, something quite simple.

Well, I would like to visualize that data in some app on android mobile phones. But some existing app that I can download from the play store.

I would also like to rely on some basic example of https://github.com/espressif/esp-idf/tr ... /bluetooth because I use idf to program my esp32 and not arduino.

In arduino I have seen many examples, but for IDF I have not seen anything that is very clear to me, I have no experience in the use of bluetooth with the esp32.

I would appreciate if you could guide me which example esp-idf can be used and which app to install on the mobile phone to be able to send these data via bluetooth and display them on the phone, in the simplest way possible, I have no power restrictions, I can use the bt classic if it is easier than with the ble.

Thanks in advance.

Hello, please can someone give me some guidance on how to get started. Thanks

You should check mit app inventor. There are a lot of examples on how to build an app that sends and receives data via BLE o classic Bluetooth.

For example: https://community.appinventor.mit.edu/t ... ide/1980/3

yes, I'll look at it...but I'm not interested in doing it with the arduino ide but with idf...I think I'll try with the esp-idf examples.
I will try with the provisioning examples on BLE and the espressif app.

Thank you very much.
