What do you mean by "seem previous program still works and new program not flashed yet"? Is the code from the last example still running on your board? Or are you able to flash the previous example again, but not able to get ble_app_uart to work? What example were you running before? Have you flashed the softdevice?

can you tell me how to program softdevice use STlink

[Jørgen Holmefjord]

If you have setup Keil to flash the application using the ST-Link, you should be able to flash softdevice in the same way described in my above link. In general, we do not support STLink, only Segger JLink. There are some posts here on DevZone about STLink and openOCD, you should search those and see if you can find an answer.

thank for reply , i want to use ble exam, but i don't program softdevice for NRF. Maybe that is the cause . I don't have Jlink , i have stlink so It's quite difficult to program softdevice for NRF52832 because KeilC only support Jlink to program softdevice . I learned that OpenOCD can help with stlink but I do not know how to use it . Can you help me ? thank

You might learn some from this blog post by one of the community users. I don't have or have used STLink, so I cannot provide any detailed help on this matter.
