nRFUart Example - "Exception in StartMasterEmulator: -100"

[awneil]

I have tried using the pre-built nRFUart Example in the Master Emulator API (2.1.11.1) and get the above error

I also tried rebuilding - no change.

I do have a PCA10000 dongle with the Master Emulator loaded, and Master Control Panel works fine with it:

So what's missing?

Running on Win7-Pro.

Edit:

Updating the Question, as the comments can't show images or fixed-format text.

After the update, the nRFUart example looks like this:

But pressing the 'Connect' button does nothing at all.

The Log File is attached:

I believe the nRF Uart example is failing because it uses a baudrate that is not correct for the firmware you are using. At least it looks like it from the logs. MCP will detect and set the correct baud rate when you program the chip. Master Emulator does not detect this and will have to be configured manually. The correct baudrate for MEFW 0.9.0 is 115200, default for Master Emulator is 1000000.

[awneil]

OK, that sound plausible - but how does one manually configure the baud rate? There is no settings menu anywhere. I don't see anything obvious in the source.

[awneil]

So I found the SerialPortBaudRate property - but no information or example on how to use it.

So, in InitializeMasterEmulator(), I just added

        masterEmulator.SerialPortBaudRate = 115200;

immediately after

        masterEmulator = new MasterEmulator();

And it does now work!

[awneil]

So, at least, the documentation needs to be updated:

1. To explain that this is necessary;

2. To explain how to do it.

Preferably, the examples should be updated!

There SerialPortBaudRate property is listed in the .chm documentation with a short remark on usage. It's not very visible I agree. The examples should also use this property even if it's just setting the default value, making the usage is more visible to the user.

[awneil]

Yes, the .chm lists it - that's how I found it - but gives no indication of how or where it can or should be used.
