问题 I am currently trying to develop and application that allows users to bond to a Peripheral via a click of a button and the password will be automatically entered. Is it possible to Bond and Remove Bond programmatically using swift? 回答1: Pairing is initiated any time that you attempt to write to or read from a characteristic on the BLE device. However, if the device is not set to require authentication and/or bonding, you will not see the iOS popup which requests the PIN code. I struggled with

问题 I have been digging all forums and tutorials about transmitting in background mode with iBeacon. Until now, I couldn't find something solid which can help me. My app can successfully receive and transmit but when I press home button, transmitting stops and connection on other device/devices disappear. In myApp.plist, I added required keys but still nothing works. The question is, how can I make my app keep transmitting in background mode? 回答1: iBeacon will not advertise (transmit) in the

问题 Just making this to see if someone could help me with some BLE problems. I'm trying to make an app which gets the stuff from my rowing machine but I can't figure out how to turn bytes into like a string? Its hard to explain but here's my VC: import UIKit import CoreBluetooth let rowerServiceCBUUID = CBUUID(string: "CE060000-43E5-11E4-916C-0800200C9A66") let characteristic1CBUUID = CBUUID(string: "CE060031-43E5-11E4-916C-0800200C9A66") let characteristic2CBUUID = CBUUID(string: "2AD1") class

问题 I am having a hard time getting a valid value out of the HR characteristics. I am clearly not handling the values properly in Dart. Example Data: List<int> value = [22, 56, 55, 4, 7, 3]; Flags Field: I convert the first item in the main byte array to binary to get the flags 22 = 10110 (as binary) this leads me to believe that it is U16 (bit[0] is == 1) HR Value: Because it is 16 bit I am trying to get the bytes in the 1 & 2 indexes. I then try to buffer them into a ByteData. From there I get

问题 I'm trying to retrieve my peripheral's Firmware Revision String. When Interrogating my peripheral through the app "LightBlue" I'm able to view the Device Information which includes: Manufacturer Name String Firmware Revision String However, in my code I'm unable to discover the characteristic for Firmware Revision String. I've tried the following UUID's: 2A26 0x2A26 2a26 0x2a26 How do I go about retrieving the Firmware Revision String? 回答1: You need to first discover the relevant CBService.

问题 I know lost of questions are there related to this, but didn't get the proper solution so can you please help me. I'm stuck here from last 2 days Can we search the Bluetooth/BLE devices when app is in background. Can we search the Bluetooth/BLE devices when app is inactive mode 来源： https://stackoverflow.com/questions/63394414/how-to-search-the-ble-bluetooth-device-when-app-is-background-or-inactive-state

问题 My app is running as a Bluetooth LE peripheral, and I'm trying to send just a few bytes of custom data in the Advertisement. func btStartBroadcasting(peripheral: CBPeripheralManager!) { // create an array of bytes to send var byteArray = [UInt8]() byteArray.append(0b11011110); // 'DE' byteArray.append(0b10101101); // 'AD' // convert that array into an NSData object var manufacturerData = NSData(bytes: byteArray,length: byteArray.count) // define a UIUD for the service let theUUid = CBUUID
