It appears my earlier conclusion of a bug in AximsiteWirelessPower was incorrect. At mikelspikel's suggestion, I did organized testing (reported in detail below), and AWP now seems to be working just fine. I don't now know what the issue could have been before.
Thank you, mikelspikel for requesting I do a full test to verify my claim, which turned out to be incorrect. I apologize, and will work at being more careful before making such claims in the future.
Also, thank you mikelspikel for using the term AVRCP, which prompted me to read up on A2DP and AVRCP more. I'm still not sure I understand them well, but at least now I have a better idea than before.
Here is a complete log of the testing I did if anyone cares to read it all:
BlueTooth A2DP/AVRCP testing - written in real time as testing proceeded.
Given:
- x50v WM5A02 ("axim")
- Native Microsoft BT Stack (no tweaks/hacks, etc.)
- Windows Media Player 10 Mobile V10.2 Build 14957 ("WMP")
- CorePlayer v1.0.4 build 716 for ARM ("CP")
- (see "View MyPDA" for additional info)
STEP 1 (AximsiteWirelessPower.cab ("AWP") is not installed):
a) Soft Reset (from MagicButton menu (typical unless noted otherwise)
b) Launch BT from tray icon and connect Plantronics590
c) Launch WMP and play WMA music stored in Library on SD
d) RESULT: 590 has control of volume, track advance, track retreat, and track pause. 590 controls will not restart song play. ("full control")
STEP 2 (AWP.cab is not installed):
a) Close WMP, turn off 590, turn off BT from tray icon, Reset axim
b) Launch BT from tray icon and connect Plantronics590
c) Launch CP and play WMA music stored on SD (same tracks as Step 1 but using PlayList)
d) RESULT: 590 has control only of volume. (590 does not have full control.)
STEP 3:
a) Close CP, turn off 590, turn off BT from tray icon, Reset axim
b) Run AWP.cab from SD card (using Total Commander "TC")
c) Install "Aximsite WirelessX51" to "Device"= successful
STEP 4:
a) Reset
b) Launch BT from tray icon and connect Plantronics590 (x50v response time is slower than during previous steps - battery is low, though - plugged into AC power - I started testing with a partially charged battery)
c) Launch WMP and play WMA music stored in Library on SD
d) RESULT: 590 has full control.
STEP 5:
a) Close WMP, turn off 590, turn off BT from tray icon, Reset axim
b) Launch "WirelessPowerConfig.exe" (from TC) (the system retained my old settings from previous installation as follows:
Control WiFi, Control Bluetooth, Icons show desired state. Direct, One keypress toggles WiFi, 1000 Milliseconds. Blue, Grey, Green, Grey
c) Launch "WirelessPower.exe" (TC), connect 590
d) Launch WMP and play WMA music stored in LIbrary on SD
e) SURPRISE RESULT IS SAME AS STEP 2 (CONTRARY TO REPORT ON ORIGINAL POST): 590 has full control.
STEP 6:
a) Using AWP (Launched from button 6), shut off bluetooth
b) Using AWP, turn on WiFi, launch IE, and read news for a few minutes.
c) Close IE. Using AWP, turn off WiFi.
d) Using tray icon, turn on BT, and connect 590
e) launch WMP and play WMA music stored in Library on SD
f) RESULT: 590 still has "full" control!
g) shut down WMP, turn off BT from AWP, turn off 590
Step 7 (Now I'm really wondering what's up because everything with AWP seems to be working fine now when I had thought it wasn't before I made my original post):
a) reset
b) Turn on BT from tray icon, connect 590, Launch WMA, play music
c) RESULT: 590 still has full control
d) turn off 590, turn off BT from tray icon, (sound plays from axim), close WMP
e) turn on BT from AWP, turn on 590, 590 connects
f) Launch WMP and play music.
g) RESULT: 590 still has full control.
