The idea is, in the app you scan a list of BLE devices. You select one (or more) from it, and once any of those connect or disconnect with the phone, the app can be triggered and send a notification…
I'm using CoreBluetooth to listen to advertising data to extract the bytes I need from the BLE device I have, specifically the manufacturer data. I've verified my application and the code as working via Mac as a silicon app and…
I'm learning to use Beeware to create mobile apps that access Bluetooth devices that I created. I'm coding on a Mac M1 Airbook running Sonoma with VSCode. So I gathered that although Beeware does not by itself have Bluetooth LE…
My app is connected to BLE accessory using CoreBluetooth state restoration and preservation (SRP). This means that the native part of the app can receive HR samples continuously even when the app is in the background. However, what I can…
I'm trying to send data over BLE from my iPhone to an ESP32 board. I'm developing in flutter platform and I'm using flutter_reactive_ble library. My iPhone can connect to the other device and it can also send 1 byte using…
I'm currently developing a react native app in combination with a device. The device and the app communicate via BLE. So far everything works as expected but I'm having issues with the connection stability of the iOS app and the…
Xcode build doesn't recognize a byte array sensor_data_bytes defined in C++ .cpp file. It does, however recognize a char variable defined in same files and also recognizes unsigned sensor_data_bytes. func peripheral() receives BLE notification data which it needs to copy…
I'm trying to create an Obj-C, CoreBluetooth virtual peripheral app and get this warning. // // ViewController.h // sim_backend_empty3 // // #import <UIKit/UIKit.h> #import <CoreBluetooth/CoreBluetooth.h> @interface ViewController : UIViewController <CBPeripheralManagerDelegate> @property (nonatomic, strong) CBPeripheralManager *peripheralManager; @end // // ViewController.m //…
