Gatt max size and number of connection count to change in Relay_hrs example

[sowmiya]

Hai ,

  In my application i should connect parallel connection and peripheral and central part connections simultaneously.

for this i developed from hrs_relay example .in this example by default NRF_SDH_BLE_CENTRAL_LINK_COUNT  has given 2 and NRF_SDH_BLE_GATT_MAX_MTU_SIZE is 23 .

i need to change both i have to more central connection at same time,

so i change values to increase after changing nrf gets resetting due to ram memory size issue ,its doesn't showing any ram size to increase 

how can i increase this ?

when i tried with ble_app_blinky_example when i incresed the gatt_size and central count showed the ram size to increase..

how to change here??

so i change values to increase after changing nrf gets resetting due to ram memory size issue ,its doesn't showing any ram size to increase 

It is possible that this might be a different RAM issue than the initial check softdevice and the application does at the time of softdevice_enable. What/Where exactly is this RAM issue in your code?

when i am running code in gatt init function max will set there its get a no mem ram size ,

now got a solution when i incresed  ram size its working fine...

thank you

 in my apllication i m using ble_app_multilink_central example for connecting with multiple peripherals.

how to connect with multiple connections ??

tried with one peripheral to connect with mac id  connected but i need to add multiple connections of peripheral  connecting with mac id

and also it sholud be always in connection mode 

could you explain ??

Hi Sowmiya, 

The multilink central example have the capability to connect to NRF_SDH_BLE_CENTRAL_LINK_COUNT(8) peripherals. I do not think we have any example to show the multilink peripheral, sTo be able to compile your project to have multiple peripheral instances, you should change NRF_SDH_BLE_PERIPHERAL_LINK_COUNT in sdk_config.h file to how many concurrent instances of peripheral you want to have. And in the BLE_GAP_EVT_CONNECTED event of the peripheral, you should start connectable advertising again so that it will be able to connect again.
