ble_app_uart won't advertise as coded from example set

[Alexandre Tessier]

Hello, I am currently trying to program the uart example code from the nRF5_SDK_12.3.0_d7731ad zip file. After dealing with various reference address and device package issues, I am now able to flash the softdevice and progam sets to the chip. However, the chip is not advertising and it does work with the premade hex file. At this point I have no idea what could be wrong, the only noticible difference between the hex file layout in nRF Connect and the flashed softdevice and code from Kiel 5 is shown in the attached image, with hex file on the left covers the register address from 0 to 0x0001E3F7 while the flashed program from Keil goes from 0 to 0x0001E3FF. Other than that the recovery error is shown in the command window, but this occured even for the hex file which would advertise so I am unsure how to proceed.

Hi

Is your hardware a QFAA or a QFAC build? You should set the device to match your actual HW. When you have done so, make sure you have installed a supported version of the MDK and device family pack for Keil 5 and the nRF51. Explained by my colleague Kenneth here.

Best regards,

Simon

Hello Simonr,

At the momen I'm using the DK, the current issues are occuring on the DK and I haven't tested it on my actual hardware yet. THe hardware in question follows the QFAA build. I am not aware of any aspect in Keil that needs to be set for the specific build, mainly just choosing the type, ie. xxac or xxaa. I have just realized that when I look at the devices listed in the Pack Installer, the only ones available are 8.44.1. However, as can be seen in the second image, I can only get it to run with 8.11.1. Is this what may be causing issues?

Sincerely,

Alexandre Tessier

Followed the suggested corrections, it now works with the appropriate 8.44.1 startup update, however still no advertising found.
