So this should be the solution on jasbur#88 ssid is not displaying last 4 serial? I already installed the version of jasbur/RaspiWIFi , how can I update so my access point is show like “MY_NETWORK1234” (where 1234 stands for the last 4 numbers of the serial of my raspberry pi) instead of “MY_NETWORK 1.1” ?

@BramWerbrouck If your /proc/cpuinfo file contains other stuff than serial number at the end, the result of

subprocess.check_output(['cat', '/proc/cpuinfo'])[-5:-1]

proposed by the jasbur does not contain last four bytes of serial. I applied more careful code which takes the serial number based on line regex match: ^Serial\s*:\s*(\w+)$ so if any additional lines follow that line, it would still be fine.

You can apply the diff of this PR to your code on your own.
