First, this is an amazing device. Just got it a few days ago and using all the features in the obi100 (call back, both sps, vg, obion, etc.)
However, having a small problem saving changes on OBiTALK. Steps (with 1.3.0 (Build: 2774)):
1. register OBI device (my case OBi100). At this point, the device data is cleared (okay).
2. go to expert configuration right away
3. go to "enter obi expert"
4. make any change (such as sp1 service) and press "submit"
5. log directly into OBi device and verify that the change is made (good so far)
6. make a second change (such as sp2 service) and press "submit"
** at this point, I find that this and any subsequent change is not made to the device.
Note that above is the simplest test case; this happens even after configuring the SP1 and SP2 from OBiTALK.
For now my workaround is after step 6, I manually configure the service directly to the obi100. The device is still registered on obitalk so I still get to use OBiON.
