How to send more than 8 packets of 20bytes to ble app using notification

[Newbie]

Hello, I am using sdk12 and uart code. I want to send my sensor data readings to ble app. For that I have modified the ble_app_uart code and I am able to send 8 packets of 20 bytes using ble_nus_string_send function. But my challenge is I am not getting more than 8 packets in the app. I think that the queue size is set to 8. Which buffer should I allocate more storage?

I am attaching my main.c New Text Document (3).txt

I have checked the error code of ble_nus_string function. It returns me success until it sends 8 packets and than it returns error after 8th packet.

This code will send what you have stored in data to the UART module, and the data will be printed on the terminal when you get the BLE_GATTS_EVT_WRITE.
