Using with a Treo 650 (Cingular)

[stevenf]

I got my 770 to pair with a Treo 650 after some finagling. There are two tricks to this:

- The Treo has to be put into DUN mode before the 770 attempts to discover it. (The Treo has a terrible bluetooth implementation. It can do DUN, but enabling DUN prevents any applications on the Treo from being able to access the data network.) If you don't enable DUN on the Treo first, the 770 will report that the phone does not support the required services.

- You have to specify a CID in the dial string. The 770 defaults to dialing *99#, but it only worked for me after I changed it to *99***1#

- The settings I use for Cingular's unlimited Data Connect plan are: isp.cingular (APN), ISP@CINGULARGPRS.COM (user name), CINGULAR1 (password)

So, this got it basically working, but I still have one big problem. Every time I initiate a DUN connection from the 770 to the Treo, it makes me re-pair. This is very irritating because you can't just leave the phone in your bag -- you have to pull it out to re-enter the PIN for pairing every time the 770 tries to connect.

The 770 shows up on the Treo's "trusted devices" list, so I have no idea why this is happening. If anyone figures this out, please let me know!

I had a Treo 650, and also had the same pairing issues. I was able to get it paired, but the trust was never created. I had to accept the connection on my Treo before internet would go through. I was sick of the PalmOS anyway, so sold it on eBay and got a Nokia 6682 - problem solved. The only thing I miss is the full keyboard.

I have to pair it everytime on the Sprint version too. I think it's because the 770 doesn't have a discovery mode and so theres no way pair FROM the 650.

[stevenf]

There is a hack for making the 770 discoverable.. You need to enable root on the 770 and "hciconfig hci0 piscan" from an xterm.

I tried this, then paired to the 770 from the Treo, but it didn't seem to make any difference. I'm still prompted for a pairing passcode on each connection. :(

[stevenf]

Any Treo users find any hack or workaround for this yet? I've since been able to get a PowerBook and a Tablet PC online using DUN on the Treo, without having to re-pair every time. The 770 is still holding out.

Has anyone tried it with today's newly released 770 firmware?

I do not have this problem with my un-branded Treo 650. Paired once and has been working just fine ever since.

[Jeffgrado]

pdq, do you haveto enter a passcode each time? If not, how did you pair the first time?

[pdq]

No, I don't have to enter a passcode. I used the built-in wizard for pairing. At one point it asked for a pin code and the text entry field already contained a four-digit numeric pin. I confirmed that, a window popped up on the treo, I entered that same pin there. There was an error message about some features not being supported by the phone. Nevertheless, dial-up worked fine after I selected my provider (t-mobile in germany). I'm using software 2.2005.45-7 (rd-enabled with flasher).

Sprint Treo 650 works fine, but you do have to enter a passcode every time you connect. I'm just glad it works at all!

[pdq]

May be, when entering the pin on the Treo during initial pairing, you overlooked that checkbox where it says "Add to trusted devices"

[Jeffgrado]

I've tried that on the Sprint US version, and it didn't work too well. Maybe I'll play around with the new firmware and see what happens. I don't see why an un-blocked treo would work better, but maybe they had to do something different to the CDMA DUN modes.

[stevenf]

Yeah, I checkmark "Add to Trusted Devices" every time, but it never helps. In fact, it's ON the Trusted Devices list, if you look at it. Just keeps asking for the passcode anyway.

Interesting that it works for you. That suggests it is solvable, if we can just figure out what we're doing differently.

i cant seem to get mine to work. i have a cingular 650. i can pair the devices. and in my phone for the media net, my settings are wa.cingular WAP@CINGULARGPRS.COM CINGULAR1 and not the isp. when my 770 goes to dial, the light will comeon my 650, and then the 770 says connection to phone failed. any ideas?

[slackwaresupport]

update. works with my wifes motorola v551 with all the settings i have. so its just bluetooth between the devices..

[slackwaresupport]

got my 650 to work. but, i had to reflash it to the unbranded gsm firmware. works perfect now.!

[Jeffgrado]

I have a question for the Cingular or GSM users. Does your 650 pair with the 770 correctly? Do you have to always enter a passcode when you want to use DUN?

[slackwaresupport]

mine paired fine.

[stevenf]

Jeffgrado: I've had mixed results with pairing to my Cingular 650. Sometimes it will go OK, but if you delete the pairing and try again you will have trouble completing the process. Or vice-versa. But I've had a lot of trouble getting the Treo to pair with other bluetooth devices, such as my Powerbook. They all seem to work "eventually".

With the 770 + Treo combo, yes, I always have to re-enter the passcode to use DUN. With other devices + Treo, no.

[Jeffgrado]

I see there are some new firmware releases out, but I'm guessing it won't change anything! I'll try it this weekend.

Trying to connect my 770 with my Treo 650 has been an ordeal. I've found that by "disabling name cache" in the Treo 650, it tends to allow a successful pairing more frequently. Now I'm hindered by creating a connection on the 770. Spring doesn't seem to have a setting in the drop down box. Does anyone know what settings I can use for ph#/username/password?

Thanks!

I have the 6682 and i can pair but not connect to the internet. I keep getting "remote server error" HELP!!!!!

[airbillion]

I have the Cingular 2125 and also keep getting the "Remote server error. Try again?" Any Ideas?

[jimmie geddes]

I keep trying to pair it with my Sprint Treo 650 and get "pairing failed, Authentication time-out. Try again?" I can't get it paired.

[Jeffgrado]

jimmie, I find that I must turn discovery on, delete the nokia 770 from the device list on the treo, then reset it. When it comes back on, turn DUN on, and try again. Don't click on the "add device to trusted list" or whatever it says under the passcode screen, I think it messes it up somehow since they can never fully pair correctly. Unfortunatly, you must enter a passcode each use, or so I found. I just use '0'. Of course once you get the nokia to see the treo, you can turn discovery off.

Thanks Jeff, I followed your instructions and it worked!!! Thanks for helping me out.
