How to implement automatic disconnect after successful connection

[deonc_3697476]

If the CYW20719 makes a successful connection with one Bluetooth device will it still look for and try to connect with other discovered devices?

1. What document should I refer to for setting up the CYW20719 to automatically disconnect from a successful connection?

2. Is there a way for the CYW20719 to automatically stop Bluetooth scanning (to save power) after no new discoverable Bluetooth devices are found? Or should I just implement code that makes the CYW20719 stop Bluetooth scanning and go to sleep after a certain amount of time (~1-2 seconds)?

Hi,

Could you please clarify your application?

Are you using Bluetooth classic or BLE or both?

Thanks,
Anjana

Hi I am making a dual-mode bluetooth scanner so I am trying to do both. I am trying to make my application find and try to connect with all discoverable Classic and BLE devices.

My concern is, e.g., if the CYW20719 finds and successfully connect to one BLE device it will stop scanning for other Classic and BLE devices.

Hello,

1. If the CYW20719 makes a successful connection with one Bluetooth device will it still look for and try to connect with other discovered devices?

A) Its application specific. You can make it configure to discover next device after one peer device connection.

2. What document should I refer to for setting up the CYW20719 to automatically disconnect from a successful connection?

A) You can use API wiced_bt_gatt_disconnect for an LE connection. Also please have a look at our API documentation here: https://community.cypress.com/docs/DOC-15242

A) You can set the scan time out. After scan time out , you can put the device to sleep.
