问题 I'm slightly familiar with BLE and I am facing some problem with an inherited code. So the app works like that: With BLE enabled the app scans for devices The app displays the devices found The user selects the device to pair with The app pairs with the device The problem I'm facing is that after pairing several times (it varies) the phone is not able to discover devices, hence blocking the user to pair. I'm using GattServer to connect with the client device, and I'm reseting the services as

问题 I'm experimenting with creating a Bluetooth Low Energy Peripheral on my Linux computer (The goal is to send data over Bluetooth From an iPhone). Im currently using the Tools hciconfig , hcitool and hcidump . My current experiment is to advertise a Service with a Specific UUID, that the iOS CoreBluetooth Library will pick up. (Note: I'm not trying to create an iBeacon). Right now, it's actually as simple as One Single Command that is bugging me. hcitool -i hci0 cmd 0x08 0x0008 15 02 01 1a 11

iOS Apps that access the same BLE peripheral: How to distinguish?

阅读更多关于 iOS Apps that access the same BLE peripheral: How to distinguish?

I have to following scenario: My app requests and receives data from an BLE peripheral (a glucometer). It it possible that the user has another app (from another developer) installed, that also communicates with the peripheral. I noticed that my app receives characteristic notifications for requests that where initiated by the other app. This causes my app to receive some data twice. Is there any way to distinguish between responses to my request and responses that are caused by another app? Or how can I handle it? While the stack obviously knows which app a certain (read, write) response
