I'm not sure this is exactly what you are looking at, but the Panasonic PAN1322 seems like pretty close: http://www.panasonic.com/industrial/includes/pdf/electronic-components/Panasonic_PAN1322_Design_Guide.pdf
Maybe I have mixed up the product numbers a bit, but try having a look at page 52 in the PDF I linked to above, that sure looks like the PBA31309 module.
From the description at Mouser (http://in.mouser.com/new/Intel/intel-pba31309-bluetooth-module/) the PBA31309 module is based on the PMB8754 eBMU with a bunch of extra stuff added to make it a module.
My guess is that Intel has this from Panasonic or maybe it's a collaborative effort... I don't know.
Hi Flummer, PBA31309 (commercial name eUnistone) is a Bluetooth 2.1 Module with integrated antenna implementing the Serial Port Profile for control via UART commands. The Bluetooth chip inside is Intel's PMB8754, a legacy from our Infineon buy-in. The PAN1322 is a licenced copy of the same. Whichever you chose, Intel wins ;-)
We bought PAN1322 EVM & we are evaluating the module .
It works properly with our android tab which has Bluetooth version 2.0 .
While using it with android tab which has Bluetooth version 4.0
I am getting sniff mode confirmation & sniff sub rating event continuously .
We need high data rate .
So we don't want sniff mode .
Is there any way to switch off this sniff mode confirmation & sniff sub rating reply.
I am getting this while during data transfer as well .
I have gone through at command set
The command to switch off this sniff mode is
So the last byte is for switching off the sniff mode (0-on 1-off).
I have tried the above command , sometimes I am getting err – 2 . sometimes I am not getting any reply .
But even after sending this command I am getting those two response .
We doesn`t have any issue in ignoring those two response from Host controller side . But since it is going into sniff mode .
We want high data throughput . we don’t want data latency to be high .
I'm not a bluetooth expert, so some of this is over my head, but am I understanding you correctly, that you want to use the module in version 2.x mode on both tablets (the module only does version 2.1, right?), but that you are getting additional events when using the newer tablet that has support for BT version 4.0, but without using these 4.0 capabilities?
Do you think it's the module, or could it be the subsystem on the tablet that's a bit verbose or something similar?
This sniff mode is added in BT 2.1 only .
While using it with tablet having BT2.0 . I am not facing any problem .
While using this module with 4.0 the tablet is giving this request .
There is no mode called 2.x .
From BT2.1 Active/sniff/park/hold mode are available .
sniff , park & hold used to save power by switching off BT radio when there is no data transfer .
I am getting the sniff request from tablet continuously ..
Its kind of master/slave communication .
They both will exchange the various parameter like minimum time interval/maximum interval to stay in sniff mode.
I am looking for command for this module .
which can completely keep the module in active mode or increase the request time interval for sniff mode to be high .
I have tried commands to switch off the sniff mode , But i did`t any ACK from module .
Looking for Intel or panasonic FAE`s who can help us in this problem .
