Device not advertising after flasing SoftDevice

Nguyen Tuan Anh

Hi,

I am facing a frustrating problem in my project: I am using Nordic nRF51822 running on UART application SDK 11. The problem comes to when I add peer management and DFU to my project. Everythings seem working fine but when I erase my device and flash SoftDevice and Application to that device, I notice that the device does not advertise anymore util I flash Application again.

Do you have any suggestion what can cause this?

Many thanks, Tuan Anh

    Hi,

    How do you flash the application and SoftDevice initially? Have you debugged to see which state the system is in after programming the application (when it does not start)? For instance, the bootloader will not start the application if you initially flash the application without also flashing a valid bootloader settings page due to a invalid application. Then you either need to flash a valid bootloader settings page or program the application via DFU to get the correct bootloader settings for the current application.
