CC2640R2F: Central and Peripheral disconnect issue on BLE5.0 stack

Barbara Wu

Part Number: CC2640R2F

My customer is developing based on CC2640R2F BLE5.0 stack. They find even central and peripheral using CC2640R2F Launchpads and original example code of simple_central and simple_peripheral under BLE5stack folder in the latest 2.30 SDK. Unexpected disconnect issue can be reproduced in a high rate.

Operation is :

Flash two CC2640R2F launchpads, one with simple_central another with simple_peripheral under ble5stack folder.

RESET two boards, then scan and connect peripheral from central via menu. When issue shows, disconect will show both on peripheral and central side uart print out, which happen just after connect operation.

Since there is no BLE5.0 sniffer available, Can you please help to check why?

Barbara,

After further testing, I realized I was experiencing a different issue and cannot reproduce the error you are describing. Can you provide me with a screenshot of their UART output?
