Earlier with SDK 13 in custom advertisement I was able to send 30 bytes under unknown characteristics tab in Nrf connect APP but in SDK 15 I am not. Because the firmware or app getting stuck if I sen more than bytes.
Earlier with SDK 13 in custom advertisement I was able to send 30 bytes under unknown characteristics tab in Nrf connect APP but in SDK 15 I am not. Because the firmware or app getting stuck if I sen more than bytes.
Where exactly does your example get stuck? Could you try to debug the problem and figure it out? Could you also provide some logs? Also, if you could upload a snippet of the relevant code that would be nice.
Best regards,
Simon

Where does your program get stuck? Could you try to figure it out by doing some debugging? Some logs would be nice as well. When you figure out where your program gets stuck, check if that is due to some function failing, and check what the returned error value is equal to.
It is not even coming to the nus handler.
Okay, the issue might be on the app side. However, it would be nice to see if the data is actually sent. Could you capture a sniffer trace to see what's happening in the air?
You could use the nRF Sniffer for Bluetooth LE to acquire this. You need an additional nRF5x device to use the nRF Sniffer.
Best regards,
