BLE Nano Scanner

[Van]

Hello,

I have a BLE Nano (nRF51822) and I want to develop an app which will find all BLE devices around (MAC addresses and RSSI) and send it by UART/SPI . I've used nRF sniffer firmware but it couldn't find Samsung Galaxy phones. There are no problems with iPhone and Beacons, it works great, but not with Samsung. I've tried to write that kind of code myself, but result was the same. I am using scan parameters like this: ble.setScanParams(500, 400, 0, true); P.S. I've tried to develop this kind of app on Silicon Labs BGM111, but the result was absolutely same . Thanks in advance. Best regards, Van

Ok so as i was saying before - it is not problem with your scanner (central). It is just your smartphone that can't advertise (work as peripheral). BLE peripheral was introduced in Android marshmallow. I assume your sgs4 and 5 have some older Android, or just a version that cannot advertise anyway.

Thanks, that's all I need to know.
