continuous connection with BLE

[leejh]

Hello, Nordic.

I'm working on a new project. It's a method of connecting NFC data to a specific device with a mobile and receiving it every time it is tagged.

what is Important it is

1.  Do not disconnect

2. Immediately re-connect if a connection is lost

So I thought it should use Bluetooth Classic. In that case, it should be composed of Bluetooth classic chip, mcu and NFC reader.

But, I changed my mind. If this function is possible with BLE, use bluetooth and mcu as nRF model. Is it possible?

Additionally, when I testing the example for Auto-connection, I noticed that the HID examples could auto-connect.

I know that it stores the information of the device that was connected to the whitelist.

But why does not the HRS example support Auto-connection? Despite being bonded??

I will wait for your answer. 

Thanks.

Best regards,

Lee

The HRS example is for a BLE peripheral device, i.e. it only accepts connection requests, it does not issue them( this is performed by BLE centrals). Hence, the only thing a BLE peripheral can do when the connection is lost is to start advertising. After that its the Central that is responsible to sending the connection request.
