How can I Receive a large packet instead of one byte at a time with the use of this sample uart_async_api? and How can I use this sample?

Hi Jaydip,

[quote user="jaydip kavaiya"]Like I already upload code for sending AT commands to BL652 via UART and its work fine but received only one byte at a time so How this example or API helps me to get large data packet.[/quote]

If you know how many bytes you are to receive, you can use this driver to set the amount, like done here:

https://github.com/NordicPlayground/fw-nrfconnect-zephyr/blob/master/tests/drivers/uart/uart_async_api/src/test_uart_async.c#L56

It also has an API for transmitting:

Kind regards,

Håkon

Hi Hakon Alseth

Thanks for the quick response

I already see this example link someone's Thread but still, the question is How to use this example for sending AT command from nRF9160 to BL652 via UART.

Like I already upload code for sending AT commands to BL652 via UART and its work fine but received only one byte at a time so How this example or API helps me to get large data packet.

just want to know how to use this example with my uploaded Code of UART.

Thanks & Regards

Jaydip

Hi,

There's a test scenario sample available for the uart async module here which can be of help:

Cheers,
