Connect to phone in background

[Vaibhav Aggarwal]

I'm trying to get my nRF52 BLE peripheral to connect to my phone while its screen is off and it's in sleep mode. Other consumer BLE peripherals that I have can connect to my phone while its screen is off but my peripheral can't and will only reconnect once I turn the screen on. Is there some sort of setting or configuration to enable the background connect functionality? Thanks!

@Vaiblhav: Are you talking about iOS or Android ? On Android you can create a background service, like this

For iOS you may want to have a look at this.

@Vaibhav: You may need to have a look at the sniffer trace to figure out why it connects to other devices but not yours.

We need to check if the app/phone actually connect to the nRF5 or not. If it doesn't then it could be that the flag or something are different from what other device advertise to the phone doesn't send connect request.
