On the EFI Analytics Class 1 Bluetooth Adapter, it is switchable. RX TX Polarity - This will vary according to adapter and gender changers. Hardware Flow Control - This must be turned off.Įcho - On many adapters you must make sure Echo is turned off.
There for the default settings typically will not work with an MS2 or MS3 and must be configured properly according to the instructions included with your adapter. The default speed varies between manufacturers, but is commonly 19200 or 9600 baud. The Class 1 Bluetooth Adapter offered by EFI Analytics come pre-configured and we offer a utility program to configure it for proper ECU communication with a single click.īaud - Make sure the baud is set correctly on the adapter. The default settings vary by adapter, so you must refer to the manufacturers documentation. These must be configured correctly on your RS232 Bluetooth Adapter. The focus of these settings is on the Adapter, not the PC. If you are experiencing difficulty communicating with your controller via bluetooth and your adapter meets the above criteria, these are some common key settings that will cause the adapter to pair fine, but fail to pass back data from your ECU. in addition the class 1 signal can help insure you do not experience interference from surrounding EM noise. A good class 1 adapter will give you a realistic practical range to tune from a few rooms away or nearly a block away in an open area. While you will doubtfully be able to leave your laptop running in the pits while out making a pass, you can easily move around the garage or much further while maintaining a sold connection. Range - Additional Range does come in handy. If you have one with a null modem adapter, it often does not pass power through PIN 9. Some adapters use a null modem adapter to satisfy the gender change with proper polarity, others have switchable RXTX polarity.

In general you will need some for of gender change no matter what adapter you need because while you are connected to the controller you need a male pin out, but when configuring from your PC you will need a female pin out. Male DB9 connector - The DB9 must either be able to connect as a male pin out with proper RX & TX polarity, or you will need a gender changer. In testing we have found that the Class 1 adapter we offer can provide TWICE the data rate of a GBS 301 in many conditions. I don't know if there is a way to know what sort of through an Adapter is capable of without testing it. Although the capable data rate of bluetooth is well above typical RS232, it seems there is additional ping latency between send and receive that will lower potential read rate. With a carefully selected Adapter you will get a very acceptable or even close to cable performance. You typically will NOT get as fast a read rate for run time data with a BT adapter. This is likely not a big deal for normal operation, but if you are diagnosing a cranking issue you will either want a cable or a separate power source for your BT adapter.ĭata Rate / Throughput - The read rate capability is an attribute in which we have witnessed a large variance between different BT Adapters.
This will cause a delay and you will not be able to communicate with your ECU for 15-30 seconds.

However this can be troublesome if you are trying to diagnose an issue while cranking your vehicle each time you power cycle the Adapter, The PC or Android device will need to re-pair with the adapter and recreate the virtual com port. This is much more convenient and automatically powers on the Adapter when you power on the ECU. This lets you just plug the Adapter into your v3.0 or v3.57 MegaSquirt and the BT adapter will be powered by the MS with no extra power line. Power from PIN 9 - Many of the better RS232 Adapter, but not all offer the option to power off of pin 9. However there are some key features you will want to see in an RS232 Bluetooth adapter for easy operation and some limitations you should be aware of before throwing away the RS232 cable completely. It is great to just connect right up to your ECU without and cables, especially if you have an adapter that provides some range, you don't have to be in, or in some cases even very near the vehicle! now with Android support via Shadow Logger and Shadow Dash, some for of bluetooth support on your ECU is more important than ever. Wireless freedom with bluetooth connectivity to your MegaSquirt.
