Connect one pheripheral to two central

[meghna]

Hi

how to  connect  one peripheral to two central and after connection established sent the data to both central?

I am using nrf52, soft device 132 .

i am able to make connection and send data from one peripheral to one central using ble_app_uart(peripheral),ble_app_uart_c(central ) code.

Hi,

See the multi-peripheral example in the SDK. It implements exactly this behavior.

HI i want to connect one peripheral to two central and i made below changes in sdk_config.h but still not able to connect two central with one peripheral.

// <o> NRF_SDH_BLE_PERIPHERAL_LINK_COUNT - Maximum number of peripheral links.
#ifndef NRF_SDH_BLE_PERIPHERAL_LINK_COUNT
#define NRF_SDH_BLE_PERIPHERAL_LINK_COUNT 2
#endif

// <o> NRF_SDH_BLE_CENTRAL_LINK_COUNT - Maximum number of central links.
#ifndef NRF_SDH_BLE_CENTRAL_LINK_COUNT
#define NRF_SDH_BLE_CENTRAL_LINK_COUNT 0
#endif

// <o> NRF_SDH_BLE_TOTAL_LINK_COUNT - Total link count.
// <i> Maximum number of total concurrent connections using the default configuration.

#ifndef NRF_SDH_BLE_TOTAL_LINK_COUNT
#define NRF_SDH_BLE_TOTAL_LINK_COUNT 2
#endif

Any other changes required for connection?

Hi,

I just the tested the example and it should work without changing anything. Are you running the ble_app_central applications on the centrals?

[meghna]

Can you please tell me which example code you have used for connecting one peripheral to two central.

and what changes you have done for making connection one peripheral with two central.

I am using ble_app_uart {ble_peripheral code} and ble_app_uart_c{ble_central code].

Hi.

As I wrote earlier, you should use ble_app_multiperipheral on the peripheral side. You can find it in the experimental folder under the ble_peripheral examples folder. No changes are needed.
