Using the following image UUID on NRF51822, how do i connect to the host in the nRF5_SDK_12.1.0_0d23e2a softdevice? I used to the example of ..\ble_peripheral\ble_app_uart to connect to host ,but failed.

Using the following image UUID on NRF51822, how do i connect to the host in the nRF5_SDK_12.1.0_0d23e2a softdevice? I used to the example of ..\ble_peripheral\ble_app_uart  to  connect to host ,but failed.  Do you have some idea or demo for me?

What are you connecting to? The ble_app_uart central sample? This will check the advertising packet to see if it contains the NUS uuid: examples\ble_central\ble_app_uart_c\main.c-->on_ble_evt()-->is_uuid_present(). If this is the case you have to update m_nus_uuid accordingly.

You could also check out the links below, which will help you with adding a custom UUID to your sample:

• https://github.com/bjornspockeli/custom_ble_service_example
  • Look at the projects tags to find versions for different SDK's. It didn't seem like there was any for SDK 12, only SDK 13.0 unfortunately. But this tutorial should give you a general overview of how to add a custom UUID to your sample
