This week we did a coding workshop exercise: 2 teams implemented the different sides of the SMPP protocol (without speaking to each other) and this morning we tried out connecting them together.
We successfully sent a message and received an acknowledgement!
It was a lot of fun and I we learned a surprising amount about SMPP (and quite how … interesting … the standard is).
Idea for a team who are less interested in SMPP (!) – try a similar exercise implementing FTP, which is a nice simple text-based protocol. I did this once and found it extremely rewarding.
