Android BLE library - autoconnect

[vignesh-mpc]

We have developed an Android application for a customer (Ibiza) which makes use of nRF's Android-BLE-Library (https://github.com/NordicSemiconductor/Android-BLE-Library). The app is based off the Android-nRF-Blinky app (https://github.com/NordicSemiconductor/Android-nRF-Blinky). Everything is working great so far, and our customer is happy.

One of the features in the app is that it auto-reconnects to the device when it sees it advertising. This works about 60-70% of the time. There are times where it doesn't auto-connect and the user has to manually connect.

We would like to see what could be done to increase the reliability of the Android app auto-reconnecting to the device, to make that number closer to 90-100%. Would you be able to provide any insight on this? We would appreciate support to help us understand how to get the desired functionality of reliable re-connections every time the device advertises (nrf52840, using Zephyr/NCS).

Right now it looks like the only setting we have is whether or not we enable auto connection (see diff snippet below):

Thanks in advance,

Vignesh

Susheel, thanks for your response, we will try that out as well. Would you be able to direct us to someone that might know more about the intricacies of this Nordic Android BLE library, and help us deliver a more robust product? Or if you have any experiences you can share from other customers that have used this library, that would be greatly appreciated as well. Thank you!
