CC2340R5: Central connect

Ryan Li

Part Number: CC2340R5

SDK version : 7.40.00.64

CCS version : 12.7.0

I am currently developing CC2340 as Central. When I enter the BLEAPPUTIL_ADV_REPORT event in Central_ScanEventHandler() in app_central.c, I want to connect to the device.

CC2340 enters the BLEAPPUTIL_LINK_ESTABLISHED_EVENT event of Connection_ConnEventHandler() after calling BLEAppUtil_connect(), but CC2340 enters BLEAPPUTIL_LINK_TERMINATED_EVENT soon after. How to ensure that the connection can be continued and will not be automatically interrupted? Or the connection will only be disconnected when I want the CC2340 to disconnect

Hello Ryan Li,

I hope you are doing well.

A thread that might be similar to your question: https://e2e.ti.com/f/1/t/1350954/

I have assigned our BLE expert to help support you, due to holidays in Europe expect a delay up to one day.

Thanks,

Hello Ryan,

Thanks for reaching out.

I think the thread Alex kindly pointed out would be useful for you to know why the device is getting disconnected: "disconnection reason may be extracted within the BLEAPPUTIL_LINK_TERMINATED_EVENT case inside the app_connection.c file."

I would also suggest checking out our learning material for: Bluetooth Low Energy Scanning and Advertising, specifically the section about: Scanning Task 2 – Print Scanning Results.

May I ask how are you using the advertisement report information to connect to the peripheral? Are you looking for specific information in the report in order to then connect?

thanks Alex , At present, I found that it should be because I set a break point that caused CC2340 to disconnect immediately.
