Hi,

The groupbuy link is located here: http://www.e90post.com/forums/showthread.php?t=82507

I did a lot of R&D to achieve a PROcede wireless bluetooth remote access solution. To keep it short, it works without any problems with V1 in my car. However, I have to wait for V2 to finalize the concept how it is installed in the ECU box. Now, knowing that V2 will be connected to switched power, this will offer a very easy installation.

With PROcede V2, we have all those pretty power curves and settings to play with. The wireless bluetooth remote access makes that convenient to tweak.

The kit consists of:

- 2 Sena Parani SD-100 ( 1 in the ECU Box, 1 on your laptop )
- 1 PROcede Data Cable
- Power cables for car and laptop
- Everything configured to connect at power-on and to work with the PROcede
- Installation parts and manual


This will be installed in the ECU box:
SD-100 with data cable, power cable not shown in the picture



Precondition is an installed PROcede V2.

Power for the device in the car will be supplied directly from the PROcede harness and it will be connected with a data cable to the PROcede’s serial interface. This configuration will imply the removal of the wireless access when you decide to remove the PROcede for some reason.

Power for the device on the laptop will be provided from an unused USB port.

Even when your laptop would have already a Bluetooth interface you will need the full kit. The notebook can connect to the Parani SD-100 but the PROcede Reader Software is not able to open the virtual serial Bluetooth COM port.

There are other reasons as well why I would not prefer such a solution. I configure the 2 Paranis to act as a physical cable, they don't accept any requests or connections from other devices. This approach is more costly than others, but it guarantees that no other device will be able to detect or corrupt the rugged data communications. The devices will autoconnect at power-on, so if you did not use the connection e.g. for a couple of months all you have to do is to power on the Parani on the laptop side and you will be connected, even when you would have changed the laptop in the meantime.

The bluetooth system will be transparent to your computer since the bluetooth adapters will act as an invisible cable. It works on PC’s and Mac’s using a Windows emulation ( e.g. Parallels or Virtual PC ).

The downside of the wireless bluetooth remote access is the speed of the connection. Due to the serial - bluetooth - serial bridging you will have timing delays between the data packets. These are already minimized in my configuration provided. This means that the wireless access will be perfect for everything ( map & firmware uploads, user settings, ... ) except data-logging ( the limited connection-speed might not provide the data logging quality you want to achieve ).

Please come back to me if you have any questions.

Cheers
Eugen

Hi guys,

All PM's and emails answered. We have 12 people joining the group buy up to now.

Thank you,

just curious, how robust is this to interference from other devices on 2.4ghz, microwave ovens, wireless access points, etc? wouldnt it be a bad thing if the connection got clobbered in the middle of a software flash?

Bluetooth was intended to replace cables. It is very robust: http://www.mobileinfo.com/Bluetooth/how_works.htm

"Bluetooth devices are protected from radio interference by changing their frequencies arbitrarily upto a maximum of 1600 times a second, a technique known as frequency hopping. They also use three different but complimentary error correction schemes. Built-in encryption and verification is provided."

"Designed to operate in a noisy radio frequency environment, the Bluetooth radio uses a fast acknowledgment and frequency hopping scheme to make the link robust. Bluetooth radio modules avoid interference from other signals by hopping to a new frequency after transmitting or receiving a packet. Compared with other systems operating in the same frequency band, the Bluetooth radio typically hops faster and uses shorter packets. This makes the Bluetooth radio more robust than other systems. Short packages and fast hopping also limit the impact of domestic and professional microwave ovens."

Yes, if flashing is done during transmission, rather than after transmission (i.e. RAM verify, then flash) AND if the flashing process couldn't be restarted. But I doubt this is the case since the hardware is not so resource constrained.

Just let us know through what means we are all going to be paying you... Paypal an option?

+1.

[e.n335]

Yes, PayPal is an option. The connection is very robust.

did i miss the price ? or you didn't post it yet ?
thanks

It's listed in the Group Buy thread. It has to be like this, following the sponsor rules. Thank you for understanding.
