the same problem again

[kkccoo]

I had the same problem as described in the previous post:
Server started on port 8199
ADB command: C:\android-sdk-windows\tools\adb.exe
press any key to exit
accepting a new connection from /127.0.0.1
new string is : '3'
new string is : '3]'
creating command MODIFYSERVICE
read parameter: type=added
read parameter: tcp.port=8127
read parameter: service.uuid=419bbc68-c365-4c5e-8793-5ebff85b908c
read parameter: bt.address=37:60:39:FE:DD:ED
java.lang.NullPointerException

at dk.itu.btemu.cmd.ModifyService.work(ModifyService.java:28)
at dk.itu.btemu.cmd.BaseCommand.run(BaseCommand.java:47)
at java.lang.Thread.run(Unknown Source)

accepting a new connection from /127.0.0.1
new string is : '2'
new string is : '2]'
creating command DISCOVERY
read parameter: bt.address=39:81:50:EE:BF:CE

this is the stack trace I got from the following operations:
start server
start emulator 1
start emulator 2
press start server on emulator 1
press discovery on emulator 2

Please help me with suggestions.

weird, it looks like the server started (or restarted) after the devices joined. you should read two JOIN commands in the server output. The NPE you have here is because it is trying to modify a service for an non-existent device..
