Multilink central with NUS UART Client

[SaiTeja]

Hello all, I would like to establish connection between single central and two peripherals for bidirectional communication. I edited ble_multilink_central example and created multiple instances NUS Clients of it. My code is getting compiled and I uploaded it to NRF52DK. It is establishing connection with peripheral but getting disconnected after few seconds.

APP:ERROR fatal is thrown after execuing ble_nus_c_rx_notif_enable() in event BLE_NUS_C_EVT_DISCOVERY_COMPLETE.
Handles for assigning multiple instances are created through ble_nus_c_handles_assign() function in event BLE_GAP_EVT_CONNECTED.

Please help me.

Images of code snippets are attached for reference.

App error fatal

My error is resolved after assigning handles to instances after BLE_NUS_C_EVT_DISCOVERY_COMPLETE.

But now fatal error is thrown after app_uart_fifo_init(). I made UARTENABLED 1 , RETARGET ENABLED 1 and APP_FIFO_ENABLED 1 . But still the problem is existing. What may be the reason?

Can you copy paste the text from your terminal as text instead of an image? I don't think I can see everything.

Furthermore, when you get the Fatal error it is most likely because one of your functions has returned an error code and APP_ERROR_CHECK() has sent your code to an endless while loop. You should try to debug like this and figure out which function failed and what error it returned.
