i was using the serial example in examples/peripheral/serial and i Want to display integer value int i=1234 on the serial terminal(putty).I want to convert the int value to string.
i was using the serial example in examples/peripheral/serial and i Want to display integer value int i=1234 on the serial terminal(putty).I want to convert the int value to string.
if i use it in the serial program it is not working.
.

sdk 14.2.0
it is working perfectly fine..i have checked it..

i was using the serial example
is there any specific requirement of using serial example?? or else you can use uart example to print data on terminal.
