i am trying to connect experimental board msp430f5438a with cc4000 using uart, but not able to. are we suppose to use the same clocks for both? i am able to connect between cc4000 and parallax terminal and getting nmea data but the same thing via msp430 i am not able to. what may be the reason

    Baudrate mismatch, wiring problems, logical level difference, wrong polarity, data/start/stop bit settings difference - those are most popular. Put loopback in place of cc4000 and test your msp uart code - do you receive back everything you send? Check parallax and msp430 uart signals using scope, look for differences.

    yes thanks, its working now. there were baudrate problems. and is there anyway of getting the latitude and longitude from the nmea sentences without using the HAL_CC4000.h as it involves changing libraries for msp430f5438a, can we use nmea.h directly in ccs studio and try?
