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

Please check out our Adjustment of RAM and Flash memory guide here to understand how Flash and RAM (start and size) should be set up in a Keil or SEGGER project.

Seems like the project builds correctly, but what about the flashing process where you flash the project onto the board?

Regarding your final question. What pin(s) do this 2V signal go on, and is it located physically close to the antenna or antenna pin? If this is the case, then it might be affecting the radio performance. What advertising and connection parameters have you set for the nRF51?

Best regards,

Simon
