CC2640: One Peripheral connecting to multiple Centrals

Danny Chan

Part Number: CC2640

Is it possible for a peripheral to connect to multiple centrals? From ble_user_config.h that seems to be possible for 4.1 and above? Thanks. Danny

// Maximum number of BLE connections. It should be set based on the
// device GAP role. Here're some recommended values:
//      * Central:     3
//      * Peripheral: 1
//      * Observer:    0
//      * Broadcaster: 0
// Note: When the GAP role includes Peripheral and no v4.1 Controller features
//       are configured, MAX_NUM_BLE_CONNS must not be greater than 1
#ifndef MAX_NUM_BLE_CONNS
#define MAX_NUM_BLE_CONNS             1
#endif

Yes, this is supported. For more information, see the multirole project for the CC2640R2 in the SimpleLink CC2640R2 SDK or the multirole project for the CC26xx on the TI BLE Github page: github.com/.../ble_examples

Hello Danny,

The peripheral can connect to multiple centrals, you can do that by changing the number of MAX_NUM_BLE_CONNS in predefined symbols and some changes in multi.h file.
