Thread: Palmone/Treo 650 - almost working

According to the palm website, the updated ROM "optimizes Bluetooth performance for some Motorola headsets and other car kits".

I'm not exactly sure what this means, but I'm hopeful that there is something that can be done.

[cut to William Shatner] "There must be SOMEway, SOMEway to make it work"

Seriously, if this awesome software would work with the Treo 650, that would rock my world in ways never thought possible.

I'm going to re-install PhCo and start with the Sony model and see what happens.

I looked into getting my 650 to work for quite some time with Phoco last winter when I got it, and determined that while it is probably possible with the right hacking, it wasn't worth my time and effort.

As near as I could determine, the problem is in the bluetooth pairing process, in that the treo will only let you pair with the CLASS of devices that are HeadSets or Handsfree devices -- regardless of whether or not they support the handsfree or headset profiles.

This wouldn't be such a big deal if you could tell the PC's bluetooth stack to advertise itself as a handsfree class device, but the user visible options in the widcomm stack are only for Computer or Laptop. It is of course possible that there is a hidden registry setting to let you advertise as some other class of device, or that the stack can be hacked to advertise a different value, but finding this will take some pretty serious hacking.

The DUN profile serial port on the 650 is of no use, the VirtualModem serial interface that is exposed by DUN can only command the data portion of the 650's modem (at least this was the case on my CMDA 650).

In theory, this is something that can pretty easily be tested under linux since you can recompile the stack and advertise as any class of device you wish -- I just never got around to it.

Hope this helps...

..Bump...

I thought were making some progress here

Any more breakthroughs?

Also, has anyone tried to make it work without bluetooth, meaning just connected via the USB cable? Not optimal, but would be acceptable until Treo's bluetooth stack emerges from the dark ages.

HI, 5 year Palm OS Developer here. 2 years ago I did a Palm Bluetooth project where we tried to implement A2DP (an Audio Streaming Profile) to interact with a headset. Turns out the headset didn't implement part of the profile correctly! Anyways we ended up making a P2P File Transfer program (yeah Bluetooth P2P hehe it was cool though!) called BlueView. Check it out if you want (ignore slow arse comcast and other broken/outdated parts of the site).

Anywho, to correct you, the entire OS is in the dark ages :P ugh it's ugly.

However (seriously) it does support the Serial Port Profile from the Bluetooth Library. It also supports the Object Push Profile natively, and a few others. What profiles exactly are needed for PhoCo to work? I just took about 10-15 min to read over this thread.

Hi Phylar,

glad we found a developer who enlightens the darkness of PalmOS

What PhoCo basically needs is a way to access the phones internal modem which is then controlled using the AT-Command Interface.
Usually, a phone that offers Bluetooth also offers a SPP (it wouldn't make much sense without) and furthermore it connects that profile to the internal modem.

I was assuming it's the same for the Treo but maybe you can tell me if I'm wrong.
Maybe it's more like the WindowsMobile where the internal modem is completely hidden to the outer world. You need special drivers to control the phone.

Did you ever try to connect to the internal modem from your PC using Bluetooth?

So you guys have inspired me to start trying to get this to work again...

I actually made a call with my Treo 650 using PhoneControl... but that's about it. It used COM8 via bluetooth, but the phone tester app never sees this as a valid port (gets no response).

I did the configuration wizard, and I think I chose Sony Ericsson (first model in the list). I manually dialed a number and it placed it. I wasn't able to dial my cell phone's number and have anything happen in PhoneControl, but it is progress. I've attached my log file.

Not sure how to incorporate the PalmOne configuration from the PhoneControl.net forum. When I cut/pasted it into the configuration file and re-ran the wizard, it didn't come up as a choice.

Some specifics about my phone: Cingular GSM (unlocked), Firmware: 01.28, Software: Treo650-1.13-ROW, with bluetooth DUN turned on.

Also, I did try the hyperterminal commands as listed in chapter 10 with success. It is definitely accepting AT commands over COM8 in my case.

Here's another log file.

Nope I have not. It looks like internally there is an AT command interface according to a skilled Treo 650 hacker, but that doesn't seem to be exposed at the API level. So yes, like WinCE there would need to be a driver AFAIK.

I do have one idea for a quick hack that might work, I'll give it a try tonight.
