hi, I am using the nrf51422 for the first time. I need to connect a GSM-GPS module for reading nmea string. I have to use the uart to enable communication with the GPS and I would use the interface ppi to capture the data and put them in a buffer until the arrival of carriege return. The goal is not to involve the CPU in the process of reading data from the port and only after they have arrived in the buffer to draw the attention of the CPU to the next process. E 'possible to realize a code in this way. If it is possible you can give me some advice. Best regard
