I have a Pixel 2 with Android 10 and it works fine. Did you give the requested permissions to the app after you installed it? We have observed that some phones require enabling the GPS in order to scan for Bluetooth devices so that is another thing you can try.
I just noticed this, does it mean you have been able to use the board just fine, and this issue came around for no apparent reason? Have you made sure that you have flashed a bootloader to the board?
Using the NCP for OTA typically means doing OTA through the NCP, so if you had written on your first post what you wrote above it would have made your use case really clear.
That seems to be a Bluetooth BR/EDR (Classic) and BLE, so that explains why you get the device name.
Do you have any example?.
You can use mbedtls to encrypt the data. Here is how to include it your project: https://docs.silabs.com/bluetooth/latest/general/security/using-mbed-tls-with-ble. You can find a lot of information about encryption and mbedtls APIs if you just look on google. But you need to encrypt the data on the iPhone side as well and we can't help with that.
This means BLE can only read the device name if the advertiser is also a BLE. And Bluetooth classic can read the name of Bluetooth classis and BLE. right?
No, don't mix BLE and Bluetooth Classic because they are separate things. Just check if what you are using to scan for the iPhone is with Bluetooth Classic or BLE. Also, the iPhone doesn't send BLE advertisements by default, you need a BLE app for this, did you write one yourself?
I would like to discover only a secured/selected devices. Can I use a string in the advertising data that others can not decode?. How can I achieve this?. Do you have any tutorial?. thank you.
You can encrypt the data on the advertisement packet using a key that only your scanning devices know, that is one way to do it. We don't have a tutorial on how to do this. What is your use case here exactly?
