Discovery failed with nRF51-DK and MasterEmulator dll

[MR]

Hi

I try to write an application in C# with the MasterEmulator dll (Version 2.1.12.6). It works with the dongle, but not with the nRF51-DK. I can open the Device but I can't start discovery. I always get the error "Failed to start device discovery". The Pin P.030 is connected to GND. I have tried the MasterEmulator examples with the same result.

But with the MasterControlPanel it works without any problems.

What am I doing wrong or it is not possible at all?

Hi MR,

I'm testing here with the PCA10028 DK v1.1.0 without having any trouble. I flashed MEFW nRF51822 0.11.0 and tested with the nRFUART example at C:\Program Files (x86)\Nordic Semiconductor\Master Emulator\2.1.12.6\Example code\nRFUart. It worked normally. Same with MCP software.

Could you try again with the nRFUART example ?

Hi Hung Bui

I solved it with your help. The problem was, that I have flashed the nRF with the wrong Image (MEFW nRF51822 0.9.0). With 0.11.0 it works fine.

Thank you MR

@MR: I'm glad that it worked. I guess you would need to configure the baudrate in the C# source code to match if you want to use with MEFW v0.9.0.
