Yes, you can use the DTM feature in nRFgo Studio for nRF51822.
If you have a look at the nRF51 SDK, there is an example firmware called "ble_app_dtm".
Program this into your device (it's setup in S110 settings, so remember to have S110 present on your device), and then the default UART is:
Pin 1 = TXD
Pin 3 = RXD
Connect these (and GND) to your UART, select COM-port from the drop-down meny, and the test should start without any issues.
From doc "nRF51822_Developer_Kit_User_Guide v1.2.pdf"
Section 8 Testing the physical layer with Direct Test Mode
it is stated:
DTM testing requires that you program the chip with the DTM application that is delivered with the nRF51
SDK as described in section 8.2 on page 45
Section 8.2 discusses ble_app_dtm.uvproj, but there is no mention that the Soft Device should be programmed.
Futher Issues: (I would have uploaded the images but I only have the option to load from a URL when replying - so forgive the verbosity)
When I load Soft Device and then compile and load the un-editted ble_app_dtm.uvproj, I get the following error:
Error programming device
Programming failed
writing to flash failed
ERROR: Segment was attempting to write in protected area! aborting..
I then noticed that the default ble_app_dtm.uvproj IROM1 and IRAM1 settings (from "Project -> Options for Target -> Target") are:
IROM Start = 0x0
IROM Size = 0x40000
IRAM Start = 0x20000000
IRAM Size = 0x40000
(default ticked for both)
So I changed these values to the same as the ble proximity project options and I can now load both Soft Device and then ble_app_dtm.hex.
In every case: I always have the same problem that nRFgoStudio crashes (ungracefully)
"nRFgoStudio.exe has stopped working"
"Windows is chcking for a solution to the problem..."
