Hi, We are developing an app for secure printing using a BLE RFID reader. What we'd like to accomplish is the ability for a user to walk away from the printer (BLE RFID reader) for any time period (10 mins, 1 hour, or 3 hours) with the app still running background mode but out of range from the RFID reader, and walks back to the printer (BLE RFID reader) and be able to connect to the reader thus enabling printing. We've noticed that when the phone is out of range from the BLE reader and phone auto-locks, the background scanning process is terminated after a few minutes. Is there a way to accomplish the above? Any help is appreciated. Thank you, Marlon

We have a BLE app and we are trying to get it to work in Background Mode consistently. Use case: RFID BLE reader is attached to a printer Person installs the iOS app on phone and enables Background Mode Person walks to the printer with phone iOS App connects to RFID BLE reader and authenticates to allow secure printing Current status/Problem: On several tests, we were able to connect to the BLE device, but with inconsistent results. For example, for 5 - 2 min tests - (1) we see 8 successful scans, (2) 1 successful scan, (3) 20 successful scans, (4) 15 successful scans, and (5) 11 successful scans. In the above tests, we were getting a scan every 3-4 secs and then it scanning stops. The objective is to maintain continuous scanning until user closes app or disables background mode. Why does scanning stop? How can we make scanning continuous? Any guidance you can provide is appreciated.
