iam Beginner to PI3 iam facing one problem in the Raspberry Pi3

currently i want to do serial Communication on the UART pin 14 and 15, where i have done loopback, Problem i faced is iam not able to send any data

Task done As Raspberrypi3 ttyAMA0 is assigned to bluetooth , so iam using the ttyS0 ,where iam using gtkterminal for configuring the port and send the data

by help of website help , i changed the config.txt by including the Enable_uart=1,core_freq=250 and even though non of the data is flowing

so kindly any one can help me to solve this problem

if you're not using Bluetooth you can disable it or switch the ports by adding pi3-miniuart-bt or pi3-disable-bt. check /boot/overlays/README and run this systemctl disable hciuart. I just disabled Bluetooth on mine and got back "ttyAMA0" everything working as it should.

On another note i think you don't need to set core_freq if you use enable_uart=1.
