Hi there,
I am working on a project where my team needs to build a heart monitor that sends data to a smartphone application via bluetooth.
我已经开发了一个简单的iPhone application which behaves as a central by looking for any advertising peripheral and read the messages available.
I ran the proximity fh_proxr_sdk on the DA14580 and my iPhone application successfully recognizes the device. My next step is to successfully send a "Hello World" type of message to my application. This is where I am stuck; From what I understood, I need to call the KE_MSG_ALLOC function and use the returned struct as a parameter for the ke_msg_send function. I am having problems on finding out what exactly to use for the KE_MSG_ALLOC parameters.
Could you please help me with this?
Thank you,
Francesco
Hello Francesco, I would suggest to look at the sample128 example.. see section 10 of UM-B-003.
Definition of the kernel messaging can be found in the following document.

Hi JE_Dialog,
I followed the steps on section 10 and 11 of UM-B-003 but I am still stuck. Now these errors:

Besides, I am still confused on how all of this works. I would have no idea on what would be the next step in sending the "hello world" message.
Is there any tutorial or example code that show how to send a simple message to a smartphone?
Hello Francesco, later in March/April we will come with some simplified examples in a new SDK release. Right now we have a very open SDK... this gives great flexibility, but is more complex to navigate, no debate on that. Until that time in March/April, the other appraoch you could take is to use our custom serial profile, DSPS. This also comes with an iPhone/Android app.
It might be a bit overkill, but if you are looking for something quick and simpler out the box, it is a good starting point.
