Connecting one central with multi peripherals - a customized ble_app_uart example

[SSSAg9]

Hi everyone, 

I'm working with the BMD-350 Evaluation Board based on the nRF52832 BLE SoC and currently using a customized version of the central ble_app_uart example from SDK13 (S132, pca10040).

In my application I'd like to connect one master with eight nodes as slaves, so by increasing the number of central links I will have: 

#define NRF_BLE_CENTRAL_LINK_COUNT      6                                                                /**< Number of central links used by the application. When changing this number remember to adjust the RAM settings*/
#define NRF_BLE_PERIPHERAL_LINK_COUNT   0                                                                /**< Number of peripheral links used by the application. When changing this number remember to adjust the RAM settings*/
#define NRF_BLE_TOTAL_LINK_COUNT         NRF_BLE_CENTRAL_LINK_COUNT + NRF_BLE_PERIPHERAL_LINK_COUNT     /**< Total number of links used by the application. */

As suggested I adjusted the RAM settings by increasing the size. However, by changing the RAM settings the application doesn't work properly.

Do I have to change other settings that I'm not considering; how can i calculate the exact value of RAM origin? 

Thanks so much in advance!!

Hi 

I made an un-official example a while back showing how to use the ble_app_uart_c example with multiple links:
https://github.com/NordicPlayground/nrf52-ble-app-uart-c-multilink

Possibly you can have a look at that and see how things are implemented. 

As suggested I adjusted the RAM settings by increasing the size. However, by changing the RAM settings the application doesn't work properly.

Are you able to provide some more information about what doesn't work?

Doesn't it boot at all, or does some error or assert occur during execution?

Best regards
