PCB v3.2 (BOM unchanged)

I've posted the latest PCB revision in the forum.

Mainly cosmetic changes and improved the layout.

BlueSaab v3.1 BOM & PCB

I'm getting a lot of requests for the BOM & PCB, so here they are. I'm also posting this in the forum.

BlueSaab Forum

At Karlis' suggestion, I've added a forum to the blog so people can ask questions and add comments easier (I hope) so that it will be more of an interactive discussion regarding the development of the module.

Feel free to start using it :)

The link should be on the right side, under "About Me".

RN52 hardware

Here's ver 2 of the hardware

I've already made a v3, to fix a problem with the USB plug on the bottom (for RN52 firmware upgrades). Firmware upgrades will be rare, and in fact, future upgrades will be done via UART pins, so the USB plug is for RN52 modules with old firmware (v1.10 & older). v1.16 and above will use UART for upgrades.

Karlis has done a smashing job on the software side! The module doesn't drop out at all now, steering wheel controls work with both iPhone and Android phones, and he's also integrated bluetooth sync connect & disconnect controls via the head unit (IHU).

There are still some bugs he wants to work out, and of course, getting artist/track info on the SID is on the to-do list :)

You'll also notice the 3.5mm jack at the top. That's for the Mic input to the RN52, which Karlis & I are planning on using the vehicle's On-Star mic. So once we figure out the best way to do that, he even has the code setup to bring Siri up for a long button press :) So eventually, you'll be able to wire in the car's mic to a 3.5mm plug, and plug that into the module, and be able to talk to Siri at the press of a button (or no button if your phone is charging or you have 6S)!

Feel free to ask questions in the comments; Karlis said he'd try to answer software questions for me :)

And no, I'm not planning on making/selling them. Do you know how much work that would be for me for all of you?! But I can help guide you along the way :)

New bluetooth module; RN52

So I've been working with a buddy (Karlis) about getting a better working module. He's determined that the BC05B module I was using isn't a very good module. It's a total PITA to work with, and has very limited documentation.

He suggested that we go with a RN52 module by Microchip.

He's done a lot of testing, and I've laid out a new pcb for that module.

Karlis has also done extensive testing and determined that the CANBUS code had a lot of bugs in it, which he's kindly fixed; Thanks Karlis!!

Prototypes are being built, then tested, then should be released for everyone else to use :)

New software

A fellow Saab enthusiast, Karlis, has kindly offered to work on my crappy code and make it better :)

He's posted his new code up on GitHub here

https://github.com/kveilands/SAAB-CDC/releases/tag/v1.0

Everyone should buy him a beer for his hard work, dealing with my bad code-writing abilities :)

Bluetooth BOM for those of you who are making one anyway...

The software is still not right, but it does work...
