I have an app that is to communicate with an STM32 sending short, usually single byte, commands and receiving large packets of sensor data over BT, frequently (50Hz or so).
The app and the firmware are both written and run happily in simulation mode. They are just waiting for me to finish the...
Hola a todos.

I am developing a widget that I want to sell commercially. Doesn't do much really, a few sensors sending information every 250mS or so.
This means comms to IOS and Android phones without a local router connection ( in the wild)
The problem is that depending on the model of the users Android...
I want to talk between two mobile phones (over SIP) out in the nowhere (where I cant use normal phone call) with bluetooth headset and Direct Wifi (hopefully over 100meters) between two or more phones! I cant understand why its so complicated! OK I don't need SIP but full duplex without click...
he Makeblock robot is a low-priced kit that is easily assembled and that works well as designed. The default control sofware is effective but does not work for custom complex control sequences.
It is possible to replace the default firmware with one's own through B4R, Arduino IDE, or the mBot...
Hello.
I have a question about the bluetooth connection.
I know that here are guides on how to connect arduino with a bluetooth module, but all in the B4R program.
However, I have the entire script written in the Arduino IDE, it is very extensive.
It would take a long time for me to transform...
I have a special application where an Android device is configured as a kiosk and it is placed at a public location. Anyone having a special app in his/her phone is invited to send messages to this device via Bluetooth.
I would want my Android device to behave like a printer - user scans for...
