ble_app_uart won't advertise as coded from example set

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.

  • An additional question that has come up is there is a program that was previously used by one of my colleagues. I have noticed that when I connect with my Iphone 13, it is very sparadic when the connection is done, often disconnecting. This does not seem to happen often with my other colleagues phones, is it possible the nrf51422 chip is not adaquate for the latest models? Also, if I have a signal that is from -2 to 2 V peak to peak, will this cause issues with the bluetooth connection and cause it to disconnect?
