iOS Question Bluetooth Pairing Request issue

[echeng2]

I try to connect to a BLE electronic scale using iBLE v2.0 and bleExample. I am able to Devicefound and Connected. When I do "manager.ReadData("FFF0")", there is a message popping up from iphone saying "Bluetooth Pairing Request" and ask me to enter pairing code. Please see attached image. I can enter anything or nothing, it will work. Then DataAvailable continues and works.

I would like to avoid the "Bluetooth Pairing Request" message popping up each time when I ReadData. Is there any way to do it? Thanks in advance.

My iphone is 6s with iOS 10.3.1.

Is there an official app for this BLE peripheral? Does it show the dialog once?

Have you tried to pair the device from the settings app?

I tried the BLE Scanner from iphone App Store. I was able to connect to the BLE scale. When I tried to read data via FFF0 using the BLE Scanner app, I got the pop up message, "Bluetooth Pairing Request" from the app.

If you want me to show the B4i code, please let me know.

It behaved in the same way that your app behaved, right?

It seems like a problem in the specific BLE peripheral.

Hi Erel,

I am able to locate the official iOS app for the BLE electronic scale. The app did not show dialog (i.e. no "Bluetooth Pairing Request" dialog). When I launch the app, it is able to capture my weight via BLE right away.

Are there any ways to block the dialog in B4i? If not, do I need a new BLE library?

Thanks for your help.

Edwin

You cannot block this dialog as it is a security dialog. Is there any documentation for this scale? Maybe you are supposed to do something before reading from that characteristic.
