simultaneous Bluetooth => problem (lag)

[morpheuschen]

Hello,

my specs are:

O2 XDA neo (htc prophet) G4
Prophet ShadoW 1.0 Touch Edition GER
Radio 02.19.21
Protokoll: 4.1.13.09

Problem: If I have two bluetooth connections busy, plantronics voyager510 with during call and gps-mouse, i have a horrible lag in my navigation software (about 250-1000 metres at least. The same config works fine with headset just waiting for calls and it works great on a t-mobile sda (my last device).

I tested to activate/deactivate included gps-management, com6/com7, "eingehende daten empfangen" ("receive incoming data")

Any suggestion?

Thanks in advance (and yes, i have used the search-function including google...)
