Now, when you say a (blue) POR …are you referring to bluetooth? I am somewhat (ok, almost totally) ignorant on the bluetooth operation.
Using a tone dialer on the ‘regular’ POR worked ok. I bought an old 80’s radio shack model someone here on the forum turned me on to, and used it a few times to access voicemail.
Now that I am entering the world of Arduino, actually building my own POR is getting closer. Were it not for the (still) poor voice quality I wouldn’t change a thing on my POR. I still hope for a ‘cure’ there… The schematics released here seem to be incomplete, and not much help.
I would do a little more hands-on experimenting, but dont want to risk toasting the board. Hm. Maybe I ought to see if a replacement is available :idea: so I can ‘peek and poke’ at will.

Yes, bluetooth. I’m hoping for John Morley to login since his tinkering seems to have yielded something really nice. I too tried to make sense of the schematics, but ran into the same problem you did.
jquast:
I’ve been using port-o-rotary daily for nearly a year now, and the battery can no longer last a full day on a single charge. After 8 hours or so, even on the first call of the day, the person on the other end reports they can barely hear me, and the ringer barely or not at all rings when it should.
So looks like I need a new battery, and I see this: http://www.sparkfun.com/commerce/produc … ts_id=8484 – this would be pretty keen. Can I use this battery as-is, or do I need to make modifications, and if so, what kind?
I’m only a year late, but here’s my $0.02: According to the MCP charge controller spec sheet that is on my POR (V2.6), it is not designed for multi-cell batteries. Another thing to note is that the MCP is a fast-charger which decreases battery life as compared to a slow charger.
As for my POR, I have the same problem Jquast is having: phone doesn’t work for more than a few minutes now after 8 hours of charging. Something strange is happening, though: after all that charging the voltage at battery is supposed to be 4.2v (according to the charge controller specs), but my battery voltage is only 3.7v, still plugged in, after charging 8 hours.
I think the MOSFET might be toasted because it is a little browned. When I originally got the phone I had to get a replacement because the charger smoked that chip. My replacement still got very hot and smoked a bit, but SparkFun told me that was okay, and it seemed to work at the time.
Well, the charging circuit on the POR is toast. I accidently plugged in a 12v charger, and the blue LED never came on again. Battery doesnt charge (installed) either.
I am externally charging the battery, and looking into adding a charge circuit internally that will finally allow the phone to be on while charging. And to add a little more battery also, I picked up several of the 900mA LiPo packs. Gotta love all the room in there…
Moved the antenna to the top of the case- helped a lot with stopping missed calls!!!
All-in-all, still happy with the purchase. Good value.
Has anyone heard from John Morley lately? I’ve been wanting to talk to him about his PIC-based port-o-rotary board and possibly get the design files to make my own.
I just ordered a pickit3. But I also just compared the traces on my board against the schematic that is online and it looks like my board is different so I don’t think the latest firmware is going to work.
for example the D1 and D2 (dial tone) outputs are going to the ringer circuit.
I think there must be lots of changes to not only the firmware but to the PCB as well.
Any luck getting schematics to the custom board v2.6? I really would like to upgrade the firmware of the PIC and was expecting a serial port inside and didn’t find that.
