I meet to implement a Bluetooth master, versione 3.0 (classic) to connect to a device by uart protocol.
Which device should I use?
Tryed various esp32, Arduino Nano, but all seems supporting only BLE...
Can you suggest me right Arduino device?
Thank you,
Stefano
Esp32 (Wroom32) supports classic bluetooth.
Careful, though, since "ESP32" now includes many variants which don't support all the same wireless protocols.
Wikipedia has a nice table: ESP32 - Wikipedia
The Nanos of the 33 series only have BLE.
I second the ESP32 (models that have classic bluetooth). But you also have the option to use an Uno or Nano R3 with an HC-05 module.
Wroom32 doesn't leave space for confusion..
more details of the overall project aims would be useful?
e.g. there may be other technologies you could use
Welcome to forum.
May I suggest you to open your own topic for that for best results.
Maybe @developerstefanolenovo and @garbuiostefano are the same person…?
If so, there’s a good chance of this project going nowhere…
Or maybe not even a person...
Without offence... you can't be sure nowadays.
I would like to connect to this device:
with this specifications:
Class 1.5 Bluetooth v3.0 transmission (max range: ~ 250 ft)
Profiles: SPP
