sd_rpc_open() error code 0x0D.

[Zeddy]

Hi 

I'm testing heart_rate_collector in pc-ble-driver. in CONSOLE application, it work well.

but in Win32 Application, it doesn't work when run sd_rpc_open().

error code always is 0x0D(NRF_ERROR_TIMEOUT).

what should I do and where is my problem? thanks !

Hello,

but in Win32 Application, it doesn't work when run sd_rpc_open().

Could you describe how you are doing this? Are you only using the Windows BLE API, or are you using the pc-ble-driver as part of your windows application?
What hardware are you using for both peripheral and central?

Best regards,
Karl

Hello Carl

there is no Window BLE API , just pc-ble-driver as a part of Win32 application.

and I have found the answer why is timing out.

In Win32 application, I use 'SendMessage' to transmit and show log data but not printf().

then it will TIME OUT when opening BLE driver(sd_rpc_open()).

I have no idea why is this so, 'PostMessage' can work normally but can not transmit log data in real time.

What should I do ? great thanks again !

by the way, I use nRF51 dongle.

I thought you might have been using a non-Nordic BLE adapter for you windows computer, and thus would have had to use their API. I am glad to hear you are working with the nRF51 dongle, this will make things much easier!

Is sd_rpc_open returning NRF_SUCCESS? Could you tell me what parameters you are providing the function call that times out?

Could you elaborate what you mean by this; " 'PostMessage' can work normally but can not transmit log data in real time".
Do you mean that it is working as expected, except for some kind of delay?

Looking forward to resolving this issue together!

Best regards,

Thanks Karl, I have fixed this issue. 

now I use 'PostMessage' to show log data. it's my problem in using prameter.

thanks for your reply again !
