Hi Petter,

Can you please suggest me the sample application for multiple client? In S120 softdevice specification it is mentioned that Peripheral device supports multiple client, but I am not able to see the S120 sample application for Peripheral device with multiple connection. Please guide me.

Great! Then I would appreciate if you could accept my answer. For the future, please add unrelated questions separately. Anyways, in the peripheral role our SoftDevices can only have one connection to one central. You can still do non-connecable advertising though.

Hi Petter,

Thanks for your response. I got the NUS working with the mobile device. But the problem is that I am not able to connect multiple
mobile device with the module. When i connect with the single mobile, module is not able to advertise so the other mobile device is not able to connect. Can you please tell me how to connect multiple clients with the peripheral device ?

Thanks

I'm assuming you have got the unmodified ble_app_uart working. Following it should work. Have you tried to use the debugger? If you set a breakpoint in ble_nus_string_send(), do you hit if when you try to send to MCP? If you set a breakpoint in on BLE_GATTS_EVT_WRITE in ble_nus_on_ble_evt(), do you hit it if when you try to send from MCP?

Hi Petter,

Actually there is a problem in attaching the file. I am able to attach it but the dialog is showing no file chosen. For NUS I am adding the service library form: Manage run time variable-->nRF_BLE-->BLE_Services-->ble_nus. For implementation of NUS, I am taking help of ble_app_uart sample project.

Please update/edit your question and explain how you implemented the nus service and/or include code that shows us how you implemented it. Or even better, attach your complete project so we can test it.
