[kai19960504]

Hi All,

I want to port BPS to my custom project, I encountered the problem as the title.

When I connect and trigger the subscribe like this picture.

My project will not execute 【case BLE_GATTS_EVT_WRITE】 will be disconnected,like this picture.

Here is my project,please help me to take a look.

Lab06_BLE_AddService_BAS_DIS_BPS.zip

IDE => Segger

SDK => 17.1.0

Hello Kai!

I am not seeing the error yet, but I have reproduced it on my end as well. It seems that your custom project is based on the Blinky example, and what you have done this far is try to incorporate BPS into the mix?

Hi Elfving,

Is there any following?

Hi Elfving,

I'm very share that I use SDK17.1.0.

There seem to be a surprising number of changes between the v17.1 BPS example and your project.

I'm not sure what you mean?

Elfving said:

If you want a functioning mix of the two, you can simply add the Blinky functionality to the main function of the BPS project. 

I am trying to learn the usage of Indicate, so I need to add other Services to the Base on Blinky project.

Best regards,

Kai

I see. So you haven't really used the SDK's BPS example as a guideline for this?

I assumed you simply tried to copy the code from the BPS project to make a functioning mix of the two.

I have already used it so I will try to port BPS to Blinky.

Just comparing the BPS example to yours I see a lot of changes. Any particular reason you decided not to include peer_manager_init() for instance?

I don't plan to use the pairing feature yet.

Or does BPS have to be paired with Peer?

Can you tell me the problem as soon as possible, sorry I'm in a hurry.

Best regards,

Hi Elfving,

Is there any news?

Hi All,

If anyone with the same question can refer to my answer.

Research purpose => Add Blood Pressure Service to the project, do not use Peer Manager.

Problem => BPS does not respond and disconnects when triggering Subscribe.

Solution => SEC_JUST_WORKS should be changed to SEC_OPEN.

 // Here the sec level for the Blood Pressure Service can be changed/increased.
    //bps_init.bp_cccd_wr_sec    = SEC_JUST_WORKS;  // Nordic programming
    bps_init.bp_cccd_wr_sec    = SEC_OPEN;  // if donot use Peer Manager,you should use this code.
    bps_init.bp_feature_rd_sec = SEC_OPEN;
