Hi
We are using nRF9160 DK and I am able to transfer my data to BL652 via UART with P0.10 And P0.11 with use of This Example
But I get only One byte at a time so I read This Thread and suggestion for use this example uart_async_api
But I don't know how to use it.
Pls, tell me what API are used for receiving large packets.
Here's My code for Uart.
