Hi Greg
Reading with length = 0 means reading the entire file. In contrast to a “read of file” on desktop operation systems, please take in mind, reading and writing is “expensive”, which means it takes time. Therefore, you should only read the bytes you really want to know. You should also take in mind; the size of the communication channel is limited. Usually much smaller than 128 bytes.
You set the application ID to 0xffffff and not to 1. Could this be the mistake?
