rxlev attribute missing in cellular xml for gsmserving entry #42

Open GoogleCodeExporter opened 9 years ago

What steps will reproduce the problem?
1. Track data
2. export

What is the expected output? What do you see instead?
Old and new client should produce the same kind of data.
When looking at the XML produced I can spot a difference in the cllular data 
exported:
In the old client 0.4.99 a value rxlev was present for gsmserving cell and 
gsmneighbour.
In the new client 0.7.5 rxlev is only set for gsmneighbour, not for gsmserving.

Another difference is the wifi bssid that is separated by colons in 0.7.5 but 
wasnt in the old client.

Attached are files tracked at the same location using old and new client on the 
same Phone in 2G only and 3G only mode. They have been then edited to contain 
the sames cells and wifis, and the whitespace is edited to be better comparable 
in a diff.

What version of the product are you using? On what operating system?
0.4.999 and 0.7.5 on a Motorola Defy running Android 2.2.2

Please provide any additional information below.

One more difference in the cellular data:
For the gsmneighbour the old client had the ASU number exported as rxlev, the 
new client ist exporting the Level in dBm!

Thanks for reporting.. Fixed

Fixed, removed the colons in xml files

Accepted. Nevertheless I'm unsure on how to calculate. Wikipedia says ASU = dBm 
+ 116
(http://en.wikipedia.org/wiki/Mobile_phone_signal#ASU), but Android seems to 
use ASU = (dbm + 113) / 2
I implemented the later for now..
