get notification crash issue

[sumit1478]

Hi, I used notification .c code to test receiving data from Nexgo-POS-BLE device.It was able to recive correct data but was crashing with following error:

Notification Handler: 30 30 30 30 30 30 30 30 30 30 30 munmap_chunk(): invalid pointer Aborted (core dumped)

(30 30 30 30 30 30 30 30 30 30 30 was the data i sent and i was able to receive it correctly)

However when i used following indication fns instead of notification fns ,it worked flawlessly:

gattlib_register_indication(connection, notification_handler, NULL); gattlib_indication_start(connection, &g_notify_uuid);

I do not see the gattlib_indication_start() in the gattlib.h file. Are you certain this is part of the library? I want to use it.

@felwiz

gattlib_indication_start() is in the library:
