Part Number: CC3200
Other Parts Discussed in Thread: CC1310,

I am using UART interrupt on cc3200 for receiving data from cc1310 module.

cc1310 send data to cc3200 and get data on cc3200. But problem is that when it receive data not get full data , its getting partial data.

For example, I send "distance=123,rssi=100" form cc1310 then receive data in cc3200 in interrupt 2 time. First uart interrupt get is "distance=123,r" and Second uart interrupt get "ssi=100".

i refer code from e2e.ti.com/.../390520

Hi,

This is absolutely normal in case of FIFO buffer for UART is used. You need store data in UART interrupt routine from FIFO into buffer and process this buffer when you receive full packet.

Hi,

This depends on your data protocol. You can have data length filed in your protocol or you can wait some moment and than say "I have all data" or have some end data characters <CR><LF>, etc.
