TKS,I solute the problem,There are some bugs in the example.I have to debug one by one.

I'm not sure. Difficult to say without a sniffer trace. Do you have one?

Yes ,I use Keil5.2. I move your project to the SDK examples,it is OK .but some functions conflict with the device_manager_central.c,I modify them,now project can work.

I phone can't discover my device Name,but the android phone is OK.

What do you mean by scan? Service discovery?

I modify the device_manager_peripheral.c,now android phone can link and bonding,but the i phone can't scan the device,I don't know why.My device Generic Attribute (service UUID is 0x1801) is empty, does this reason cause the iphone can't scan the device?

Why? You have limited the flash allocated to your project because you need to do dual flash OTA? Just increase it temporarily then.

RE: ANCS add to S130

Petter Myhre — Thu, 30 Nov 2017 13:52:28 GMT

That is the complete project. What kind of errors? Are you using Keil?

RE: ANCS add to S130

Songplus — Thu, 30 Nov 2017 07:29:17 GMT

Thank you.I download the project you send for me,but there are some errors.Could you send me the whole project?

RE: ANCS add to S130

Songplus — Thu, 30 Nov 2017 05:20:30 GMT

There is not enough flash for debug,because I use dual flash for OTA.

I have tried to make an example for you. I used ble_app_hrs_rscs_relay as a starting point. SDK 9.0.0, S130 1.0.0.

I have modified the device manager library. Now each .c file has its own .h file. And the function names are not the same, so there shouldn't be any conflicts. You can find the new libraries in the project folder.

I have done very limited testing, but it seems to work.

Here is the example, extract to \examples\ble_central_and_peripheral\experimental. I used Keil.

So I guess you get a reset because of an error returned somewhere? Please define DEBUG, turn off optimizations and put a breakpoint in app_error_handler().

Yes,Petter Myhre.My production need peripheral and central operation.Be peripheral role,it can be linked by phone,but can't be bonded now.Be central role ,it can scan other BLE device,and create link,but often arise link breaking,I haven't found where the problem is.I now add the device_manager_peripheral.c to the ble_app_hrs_rscs_relay example ,program can receive the BLE_GAP_EVT_SEC_INFO_REQUEST when I use the phone Launching parting operation,then my program restart.. The device_manager_peripheral.c file manage the master BLE( such as phone) Independently,while device_manager_central.c manage other slave BLE(such as CSC device),I think the conflict can be solute,but I don't know where to start, because I don't know the BLE encryption principle .Could you show me how to modify the device_manager_peripheral.cto able bond the phone?

RE: ANCS add to S130

Petter Myhre — Fri, 24 Nov 2017 11:29:45 GMT

I see.

Adding device_manager_peripheral library to the ble_app_hrs_rscs_relay example will probably lead to conflict, but they should be fixable.

Do you need concurrent peripheral and central operation? Since you have selected the ble_app_hrs_rscs_relay example? Do you need pairing/bonding support for the central and the peripheral?

My production are developed base on SDK 9,include the bootloader , We are not familiar with SDK 12.3, although it is the newest,We want to use SDK9 for developing.In the ble_app_hrs_rscs_relay example of SDK9,I fond device_manager_central.c,in the ble_app_ancs_c_s130_pca10028 example,I found the device_manager_peripheral.c file, they are Similar.Could it work, if I want to add the ANCS to the ble_app_hrs_rscs_relay by transplanting the device_manager_peripheral.c to the ble_app_hrs_rscs_relay project? In the device_manager_peripheral.c file ,I found the bonding operation Launching by the phone central terminal.Could I use the device_manager_central.cfor peripheral device manage? I mean that central and peripheral role both use the same flash block of storing bonding message?

RE: ANCS add to S130

Petter Myhre — Wed, 22 Nov 2017 11:41:14 GMT

Please consider using SDK 12.3, if you don't have a good reason for not using it.

Yes, Bond Manager is replaced by Bond Manager in SDK 9.0.0.

How have you tried to add ANCS to ble_app_hrs_rscs_relay? What isn't working? Do you get any errors? Could you provide some more information and describe what is happening?

RE: ANCS add to S130

Songplus — Wed, 22 Nov 2017 06:28:21 GMT

At nrf51_sdk_V6.0.0,ANCS is OK ,Now I'm developping at nrf51_sdk_v9.0.0. My chip work as central and Peripheral role at the same time

RE: ANCS add to S130

Petter Myhre — Tue, 21 Nov 2017 19:01:12 GMT

Which SDK did you develop ANCS successfully with S110? SDK 9 as well? Or are you migrating to SDK 9 now? Anyways, if you are starting a new project now (on nRF51) I recommend using SDK 12.3, this is the latest SDK with nRF51 support.

BTW,dm_ble_evt_handler(p_ble_evt);Does this function include bonding either peer device and phone? If I want use phone to bonding the BLE device ,do I use the ble_bondmnngr.c to manage the phone central?
