Android Question BLE2 Scanning

[aaronk]

Hi,

I am using the BLE2 lib - https://www.b4x.com/android/forum/threads/ble-2-bluetooth-low-energy.59937/

When I scan for devices:

manager.Scan(Null)

I then put my device in discovery mode and my app finds the device.

So far so good.

I then run my app, run the code as per above, then wait 30 seconds, then put my device in discovery mode. My app doesn't find the device.

Questions:
1. Is there a timeout value for how long it scans for devices for ?
2. Am I correct if I connect to a BLE device, it will stop the scanning of devices and I then need to re-run the scan ?

Call Scan2 with AllowDuplicated set to False if you want to find the same device more than once.

There is no timeout. Though you can force a rescan with this code: https://www.b4x.com/android/forum/t...aspberry-pi-android-things.81972/#post-519129
