RN52 Limbo mode

Hi,
 
I am trying to use the RN52 module with SPP and A2DP profiles. Both of these are working well with my Android app but after a while the module enters into limbo mode (state 0 according to RN52 command reference, Table 2-10). The previous mode state was 5 (= Incoming call established). 
 
In the limbo mode, command mode appears to be working but the module cannot be connected anymore via bluetooth. The reference manual is very vague about the limbo mode. I would like to ask from the forum has anyone else encountered similar issue and what kind of steps can be made to prevent the "limbo mode"?
 
Best regards,
tipith

    Hello,
     
    can you explain how did you succeed to establish a parallel connection with SPP and A2DP? I'm trying to open both the connections but only the A2DP works well. On my module, firmware 1.16, it's impossible to use the SPP.
    Is there a particular configuration to use to have 2 parallel service working?
    Thanks,
