Now you've just changed "computer" to "WiFi module".

So the answer remains basically the same:

The first thing you need to determine is whether the problem lies with your WiFi module (in receiving the data), or with your nRF52 system (in sending the data).

[quote userid="72323" url="~/f/nordic-q-a/35787/how-to-use-uart-to-send-bigdata/137815"]I can only receive data with the same length as the uart buffer.[/quote]

What "UART buffer":

in the nRF52?
in the WiFi module?
other??
all of the above?

Or is the "computer" receiving the data via the "WiFi module" ?

I have a 2kb data. How to use nrf52832's serial port to send this data to WiFi module? Now I can only receive data with the same length as the uart buffer. Thank you.

What "computer" is it?

What type of "serial port" is it?

How are you receiving the data at the computer?

Thank you for your answer. I'm a newbie and I hope you can read my code. I can only receive part of the data. what should I do? Thanks again!
