How to submit bugs on the pc-ble-driver?

[brianreinhold]

I am trying to find where to submit bugs against the pc-ble-driver. There are two major bugs I have found

1. saved CCCDs (in a bonded connection) do not get restored when calling the sd_ble_gatts_sys_attr_set() method with the locally saved configuration data.
   1. This bug is very problematic as there is no work-a-round. One simply will be unable to transfer data to a bonded peer on a reconnect (if the bonded peer follows the spec).
   2. This bug also prevents me from invoking a service-changed event (though it is clear that the peer has enabled the CCCD in the previous connection).
2. when handling a BLE_GATTS_EVT_RW_AUTHORIZE_REQUEST the update=0 option does not work. If one gets this event one MUST update the attribute value
   1. This bug is less severe because there is a work-a-round ... update the value. It may be the same value, but you need to call the update method with the update value.

I have posted these problems to the forum for some time now but its probably better to post them directly to the pc-ble-driver development team. Looked on git-hub but could not find a way to do it.

Hi,

1. I suggest we continue in this thread regarding the issue with sd_ble_gatts_sys_attr_set().

2. In what context do you see this? If only for BLE_GATTS_AUTHORIZE_TYPE_WRITE, then this is expected and in line with the API documentation.

I have posted these problems to the forum for some time now but its probably better to post them directly to the pc-ble-driver development team. Looked on git-hub but could not find a way to do it.

Bugs for the pc-ble-driver should be reported here on DevZone.

First, the documentation on the BLE_GATTS_AUTHORIZE_TYPE_WRITE states that IF I set the update parameter to 0 then I need not set the value; the current value is to be used. However, that is not the behavior. If I do NOT set the value, the client read does not work. Fortunately the bug is not too serious, because I can just set the value to the current value. It does not prevent me from performing the operations I need to do and interoperating with clients

It is possible someone there can configure the pc-ble-driver as a Visual Studio project so I can debug some of these issues myself? Someone there must have one!

[brianreinhold]

Any news on an update? Perhaps a pre-written VS project to build the driver myself?

[Einar Thorsrud]

Hi,

You can generate a VS project by following this guide, but use the cmake generator for Visual Studio instead of Ninja, like this:

cmake .. -G "Visual Studio 15 2017 Win64"

(I do not have any updates on the issue itself.)

I was hoping someone had a completed project. I tried those instructions some time ago and gave up after two weeks. It required that one download a voluminous amount of third party software which I really don't want to do. That garbage never really cleans up after itself when you try to uninstall it.

[brianreinhold]

According to what I read in the instructions, after I download tons of third party packages and clog up my paths with all these requirements, the line you give above will build the library, not make a VS project. I want a VS project for two reasons, to build a static library that has no microsoft redistributables (the one available requires them) so I can compile a static exe without the need for an end user to install redistributables, and I want to try and debug two serious problems with the driver, one of which makes it non compliant with the BTLE standards.

The cost is great and I want to be absolutely sure that doing such will give me a VS project. Then I can go through the efforts of trying to clean up the mess left by the installs (such installs never clean up completely; that's a price one always needs to pay).

[Einar Thorsrud]

I understand. However, the pc-ble-driver is cross-platform and therefore we use a cross-platform built system for it.

[brianreinhold]

Does any engineer writing the pc-ble-driver HAVE a VS project that I could get? More serious at this stage is solving the problem that I cannot reset the CCCDs from the saved info. This prevents compliant collectors from getting measurements on bonded reconnects and prevents me from doing service changed invocations.

The redistributable problem I have solved. I finally found all 67 dlls I needed to copy with the exe.

No, not according to the answer I have gotten when I asked.

This was reported as a bug internally, but it hs not been resolved yet, unfortunately.

[brianreinhold]

If I could get a working project I could help debug this.
