Hi,
Did you find a solution in your problem?
I send an AT command which has a long reply and I cannot read whole of it.

Regards

I am afraid we cannot help you. We can only help the people who want to learn something and show some effort to widen their horizons.

Simply receive the data from UART continuously, while sending another data. You may find plenty of examples everywhere. If for some reason you cannot process the data, just store it in a FIFO implemented in software as circular buffer, and process it later.

yes sir, I am using the FIFO but I always get an overflow. So can you help me implement this one?

Just use a FIFO: http://en.wikipedia.org/wiki/FIFO

The UART RX ISR feeds the FIFO, you main application pulls out the data.That is really simple. Just google for FIFO and you will find tons of usable source code and suitable implementations.

Sir, the code I use is the one from nxp. Because I connect the Rx of my UART to bluetooth and when I send AT command through UART it reply for example its setting, etc. But the reply contains more that 16 character and the only character that I was able to read is only the first 16.

Could be useful to start with good old uart sample or you post your code :rolleyes:

thank you for the reply sir. yeah by software design but can you please help me how? because when I try to read RBR and store its content on a buffer, it can only reads up to 16 character and the rest of it were lost.

By proper software design? Data processing/buffering technique.
An UART can receive millions of characters. You need to get them from the UART and do something with them when they arrive.
