Yay! Glad I could help!

Via KZfaq comments, sorry that's too complex. Google "connecting 2 Arduinos via bluetooth" and there are some great examples!

@@MarcdeVinck I can't find any information how to communicate 2 arduinos nano 33 ble sense, for example detects the temperature of the first arduino nano sense and to receive information on the second arduino nano sense , If you have any link or suggestions it will be nice Thank you

@@chetitahrachid1495 I saw you posted on the Arduino forums too. Those examples are a good place to start. And that's the best place to get help. There is plenty of examples of passing data between Arduinos via BTle, but you will most likely have to adjust to your specific needs. If you just want the code, consider hiring someone to write the code, but I encourage you to learn more about the process and adapt available code as needed.

Not yet, but I'll add it to my list!

It really depends on the application and technology. There are lots of BlueTooth LE accessories out there, and if the remote has open pairing without any needed codes to confirm, it should be a fairly easy project. Just keep in mind, it can also get complicated really quickly.

Sadly, I don't have one to test. But since the Nano 33 BLE is an official Arduino board, I would reach out in the forums for help -- forum.arduino.cc/ or Discord -- discord.com/invite/jQJFwW7

I'm using the Adafruit code that they supply for the board, and as described in the video. Head over there to download it.
