I'm trying to discover a bluetooth device from an iOS app I developed. The device is an industrial sensor which send a measure every x ms.
I dont understand why I can see and connect to the device from my MacBook but not from my iPhone. The device is not visible in iPhone bluetooth settings. I dont find it through CoreBluetooth too (by using 'scanForPeripheral' method). Is there particular specifications on iOS?
I'm allowed to setup every data I want on the BT device (profil, CoD, UUID, etc.)
The iOS app is basic and simple. I'm using CoreBluetooth framework.

The actual bluetooth pair I am talking about is: let the app shows up in the searching list of Bluetooth of System Settings and other devices can pair to it (like we pair our device to Apple Air Pods).
But all articles I find online are talking about BLE/CoreBluetooth, I don't think these methods could make a device name shows up in the Bluetooth of System Settings.So how to develop an app performing an actual bluetooth pair? Any ideas?
The Bluetooth preferences screen only shows legacy Bluetooth peripherals. Devices advertising BLE services do not appear.
Apps on iOS do not have the ability to create and advertise legacy Bluetooth services.
If you create an app that acts as a BLE peripheral, using Core Bluetooth, and specify that encryption is required for a characteristic then you will trigger a pairing process when an app acting as a Bluetooth central on the other device connects and attempts to read/write that characteristic. Note that this requires cooperating apps on both devices.
We are working in Blood pressure monitor project . we have implemented GATT protocol in our device to communicate with iphone / iPad . so far we are using Core bluetooth framework to communicate with our device ,Its working fine in data transmitting.
But our device is not visible / listing in iPhone Bluetooth in the settings page.
please note that we are not using any MFI chip.
Please advice what we needs to be done to make our device visible in iphone's bluetooth settings page without using MFI chip.
In order for your BLE device to show up in iOS Bluetooth settings, it has to have gone through the pairing process, as stated by Larme.
To do so, the device must have one or more characteristics that are encrypted. When your app tries to read/write/indicate on that characteristic, the read will fail with an Insufficient Authentication error code, which will then should start the pairing process. See section 25.10 in Apple's Accessory Design Guidelines - https://developer.apple.com/accessories/Accessory-Design-Guidelines.pdf
Once the user has selected to Pair in the dialog, keys are exchanged to finish the pairing process. Your device will show up in Bluetooth settings at that point.
Is there a specific reason that you want the device to show up in Bluetooth settings?
We are developing an android and ios mobile app for a hardware device. We have to read files generated from the device and move it to mobile app. The device is not a low energy device. It's a Bluetooth 2.1. Currently, we are unable to pair the device with the iPhone.
We need to understand is there any restriction to connect the iphone with classic Bluetooth devices? Does the manufacture need to register under MFI? Can we use some developer license/API to start developing the app and later we go for MFI?
Can you please help me with this?
I'm working on a BLE device that part of its requirements is that it'll only use connect mode between the iPhone and the peripheral (no pairing nor bonding).
According to Apple documentation Bluetooth Accessory
Design Guidelines for
Apple Products
section 3.7 Apple is using Random device address. As much as I know, when using Random device address one need to pair (in order to get the IRK).
Is there a way to have a BLE device who works with iOS and only does connect with no pairing or bonding?
I have read the docs about the BLE for iOS, and i could see that every device has its UUID instead of mac adress for the BLE.
My question ,in which there is no answer to on the docs, is- when you turn on the bluetooth on the device ( without opening any app) , so the device's bluetooth is on , what does it advertise then, and could I discover that device or get its UUID, while his bluetooth is on,but without any app that is open.
I am pretty sure that when the BLE is on, you can discover that device, or awake him, but I wonder what data can I get from him while its on without an app .
(same for Android.. )
iOS does not advertise any Bluetooth Low Energy services that are visible to another iOS device without an app running. Once an app advertises a service you will see additional services available - device information, time service, battery level.
If you are using different Bluetooth hardware to scan then you may see some advertisements without an app but the reported UUID of an iOS device changes every 15 minutes for privacy reasons - See this answer - Corebluetooth, How to get a unique UUID?
