Now it works, thanks for your great help. now there is only one problem left, on the most example the nrf disconnected after a few seconds so that i have to reconnect.

Master controll panel says: [09:32:58.4] Received Connection Parameter Update Request [09:32:58.4] ConnectionParameterUpdateResponse sent with ACCEPTED response [09:32:58.4] Connection Parameters Update sent. ConnInterval:100.0ms, SlaveLatency:0, SupervisionTimeout:4000.0ms [09:33:02.9] Lost connection to device.

The ram start should be at 0x20002000. Also, Go to flash download and set RAM for Algorithm to Start: 0x20000000 Size:0x2000. (Options for target-->Debug-->Settings-->Flash download)

The linker should be the same for both 51422 and 51822 when using s110. What sections did you set in FLASH and RAM? Also, what error did you get in Keil with the initial settings?

In run the sdk version 5.2.msi and in the the new direction in my keil direction i copy the lbs example. Sry, i forgot to mention that i used the nrf51422 and when i use the s110 i have correct the start address for the rom. if i don´t do it i get an error.

It shouldn't be necessary to do any changes in the linker since the correct settings are stored in the Keil project. Did you place the lbs example in the new SDK 5.2 folder?

okay, i have install version 5.2, download the original ble_lbs from github and change the parameter for the nrf51422 (rom and ram size) compile it flash it. But nothing happened, same probleme as before.

I meant the Nordic example projects. The new SDK has some API changes that makes it incompatible with older projects. You can download it from the product download page at: www.nordicsemi.com/.../nRF51822 and click on the version number to access version 5.2

Hi, the lbs example is currently only compatible with s110 v.6.0. and SDK 5.2 . So it won't work if you placed the project in a different folder than SDK 5.2.
