Does a nus service data packet have to end with a NULL characterhttps://devzone.nordicsemi.com/f/nordic-q-a/9863/does-a-nus-service-data-packet-have-to-end-with-a-null-characterHi, Im trying to send data via the NUS service which is larger than 20 bytes. I understand that I have to break down the data into chunks in this case, which is what I&#39;m trying to do. However, I see that if I send exactly 20bytes from the nRF UARTen-USTelligent Community 13Sat, 24 Oct 2015 23:30:19 GMTRE: Does a nus service data packet have to end with a NULL characterhttps://devzone.nordicsemi.com/thread/36598?ContentTypeID=1Sat, 24 Oct 2015 23:30:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e9c64ade-f139-4677-a96c-024bba812dcdBernd (nvisionary)<p>Ugh. No coding late at night... I made a stupid mistake on the packetizer code on the Android app side. I forgot the 20byte corner case for modulo operation ... Now that I fixed that I can see all bytes reach the other side. Printing the data as numbers helped a lot as I could see the header information on the Nordic side but not the payload data. All good, no bugs in the softdevice code.
