Current Time Service (CTS) - Need help with creating a CTS server with iOS nRF Connect App

[MANGO]

Hi, I was trying to test the CTS example with a PCA10040 board.

I use

• Nordic's SDK 14.0

• 64-bit Windows 10 machine (the PCA10040 is connected to this machine)

• iPhone6 Plus (iOS 10)

• nRF Connect iOS app (version 1.7.5)

In the Nordic's Infocenter, it says that

In nRF Connect, create the Current Time Service (CTS) server by performing the following steps:

a. In Server Setup, click the settings button and select "Load setup".

b. In the resulting window, navigate to the \examples\ble_peripheral\ble_app_cts_c folder. Load the file cts_central.ncs.

c. Click "Apply to device" and navigate back to Connection Map.

I haven't followed that instruction. However, the current date and time were displayed in the terminal after I press Button 1 on the board.

In short, this are my questions;

• Does this mean there are Server Setup / Load setup buttons or menu exist in the iOS nRF Connect app?

I don't see anything like those.

Additionally, resulting window or Connection Map are not shown.

Or do I have to upload the ncs file using iTunes?

• Lastly, what does this ncs file do? I don't see any explanation about this file so I cannot determine whether this file is essential for display the current time.

Thanks, run_ar. I see what you mean.

I have an nRF Dongle (nRF6825, PCA10031 V1.1.0) to scan peripherals while using the nRF Connect v2.1.0 on a 64-bit Windows 10 machine.

The CTS was added when I loaded the cts_central.ncs file.

To bond, click the settings button for the server in nRF Connect, select "Security parameters", check "Perform Bonding", and click "Apply". Then connect to the device.

However, before or while connecting to the peripheral, nothing appeared when I clicked the Security parameters.

Hi, run_ar. Can you check my videos?

RECFail.mp4

RECBond.mp4

I tested this after erasing the flash to make sure that there were no bond info.

In the Server Setup mode, it cannot choose Security Parameters and I think this is a bug of nRF Connect Desktop.

Whereas in the Connection Map mode, I can choose it. Can you check this?

CTS is a native service in iOS. No need to manually create it. I assume the instructions are for nRF connect on PC.

[MANGO]

Hi, run_ar. After reading your reply, I was testing this with my Windows 10 desktop.

As you see my edited section, before or while connecting to the peripheral, nothing appeared when I clicked the Security parameters.

Perform Bonding didn't appear. Is this because I used the nRF Dongle? Can you help me with this?

Also, what about Android nRF Connect? Do I need to configure something when I test with an Android (5.0 or above)?

[run_ar]

For nRF on Android you will have to start the CTS service (I think this is alrady in nRF connect for Android, but I don't have an Android phone here right now to check). I don't think the service is supported natively, but I'm not sure about the latest versions.

On Windows: Are you sure you didn't bond to another device already? Did you disable the whitelist and make the device bondable again?

[MANGO]

Hi, I have cleared the flash so it won't connect using the whitelist.

After bonding option was enabled, HCI_REMOTE_USER_TERMINATED_CONNECTION was shown.

Anyways, can you configure bonding from your desktop when you are at the Server Setup screen?

-Best Regards

In the server setup you should choose to 'Apply to device': This way you add the gatt server setup to your device. Then in connection map you can choose the security parameters. Notice that the service will appare in this overview after adding it. So It's my understanding that the server setup is only used for configuration, you can configure security recuirements for each characteristics here, similar to what you do in you code. Then 'add to device' to run the configuration on your device.
