Will there be an example of the Nordic UART Service in the central role for the PCA10059 (nRF52840-dongle)? If so is there any timeline on release?

You can use the one for the PCA10056. Just remap the UART pins.
Except the idea is to use the BLE radio and the USB CDC interface, not the UART. On the PCA10059 the UART does not connect to the USB bus.
It seems like that you have not flashed the softdevice. Try flashing softedevice first then debug your app. Also check the linker mapping. Firmware using softdevice starts at a different location where non SD firmware starts at zero.
Flashing S140 soft device from IAR succeeded but verifying soft device from nRFgo Studio failed so I re-flashed from nRFgo Studio. Now the code doesn't run at all. Gets stuck in app_usbd.c in APP_ERROR_HANDLER()
#if APP_USBD_CONFIG_POWER_EVENTS_PROCESS
ret = nrf_drv_power_init(NULL);
if ((ret != NRF_SUCCESS) && (ret != NRF_ERROR_MODULE_ALREADY_INITIALIZED))
{
/* This should never happen */
APP_ERROR_HANDLER(ret);
}
#endif
Thanks for the hint. Now I'll track down this problem.
Are you using Options->Debugger->Images to add the SoftDevice hex file to the programming step? We find when doing so that the Erase All box is not available, which forces a chip erase from nRFgoStudio after which IAR will work correctly, albeit with an extremely slow flash download. IAR 8.32.2 This has become so tedious we are switching to SES despite having paid $thousands
The erase step is required as the debugger cannot be restarted (our experience) without a full erase.
I am on EWARM 8.30.1.17148 but I am not using Options->Debugger->Images the settings. Once the soft device is downloaded it shouldn't need to be downloaded again unless the nRF52 gets chip erased. There is an option in EWARM to download a file that I generally use although it seems that might be broken now. {Project} {Download} {Download File ...} is what I have used in the past but it seems to have had a problem this time around.
Restart after a breakpoint is hit or miss: the Monitor Mode debugging at least works some of the time.
Ah, I see .. the Erase and Download File only seem to work on our version with Debugger->Download-> Use Flash Loader unchecked; we don't have any .d or .out Softdevice files, only the issued .hex files and are reluctant to use our own conversion although I suppose we could. We can also uncheck the extra hex file option after the first session, which speeds up things. Now that your comments focus my mind, I realise that not using the flash loader works much better all round, no idea why ..

Although the EWARM file open dialog box is looking for Debug files (*.d*,*.out) there is a All Files (*.*) option and it used to work for the released Soft Device hex files. Not sure about now.
