AutoConnect with ble_app_proximity & Master Control Panel/ToolBox

[TechGeek]

Hi All -

Is there anyone successfully able to autoconnect with nrf51822 with a phone/pc/tablet? I have been trying it for the past week and couldn't get my nRF51822 autoconnect with my Android Phone or Windows 10 Tablet. Used nRF Master Control Panel as well as the nRF Toolbox apps and through the Connect with autoconnect option in case of MCP. With MCP, I was able to bond successfully.

On the device, I used my own app which has the BLE Device Manager library included and I am doing the dm_init and dm_register calls correctly. Also handling the sys_evt correctly by calling the DM's system event handler.

Since I suspected it could be to do with my own app, I tried using the ble_app_proximity and it has the same result. Successfully bonding and connect the first time. But subsequent state changes, it doesn't autoconnect.

In all of the above cases, I have been using S110 v7.0.0. In case it matters.

Anyone facing the same issue(s)? Any pointers to successful implementation would be highly appreciated.

On Android, I tested with a One Plus phone device and on Windows 10, I tested with multiple tablets and PCs.

When I use "Connect using autoconnect" in MCP (in the drop down menu), once I get out of range, the phone gets disconnected (which is as expected) and getting back in to the range, does not auto-connect. I also tried Bluetooth OFF(and later ON), Airplane mode (ON and later OFF) experiments within the range. All of them resulted in same behavior- phone doesn't auto-connect.
