Can't read from PCA10000?

[mark plunkett]

MasterEmulator Version 2.1.12.6, PCA10000 Version 1.0, MEFW nRF51822 version 0.9.0,

The log file shows the following;

However when using an older version of MasterEmulator (2.1.6.8098) the com port is opened at a slower baud rate and it works;

I wish to use the ReadRSSI() in the latest MasterEmulator, is there way to change the baud rate?

The earlier veraions of PCA10000 doesn't have chips that officially support 1MBaud, and your latest version of MCP is trying to communicate with a much faster baud rate that your board is configured for. So, what is the version number of your pca10000, or better, what is the revision of the chip mounted?

If you upgrade to the nrf51 dongle you'll be able to run with a higher baud rate for sure.

In your latest installation, you should be able to find the MEFW firmware hex file (somewhere in the installation folder). You can try flashing that with nrfgo studio, but I cannot guarantee that it will work.

I didn't see this before, under file->settings->Serial port. Maybe try changing it?

There is a function in the master emulator library you can use: MasterEmulator.SerialPortBaudRate

Go in to the API documentation located in the Nordic Semiconductor\Master Emulator\2.1.12.6\Documentation folder and look up "MasterEmulator class" -> "MasterEmulator Properties" -> "SerialPortBaudRate Property" to see how it is used.

I can see that this will help if he is using a custom application, using this API, but not how this will affect Master Control Panel's behaviour.

[Stian Røed Hafskjold]

Agree, but I can't see that he is referring to Master Control Panel anywhere. I tried in MCP with the old MEFW and the baudrate was set to 115200 automatically.

Aah, my bad.
