BECON & INFORMATION

[Nasib]

Hi.

I want to broadcast the value of some sensors. But it has to be accesible at the same time for different devices.

Up today i developed the system with a UART over BLE. 

So i have 2 questions: 

1) UART over BLE could be accesible by different devices at the same time? 
2) if i change to BEACON, how can i introduce the sensor data in the advertising beacon information? 

Thank you so much in advance. 

Best regards.

Hi Nasib

1. What do you mean by this? The nRF5 series only have one radio, so they will only be able to do one task at a time. If the device is advertising publicly it will be seen by all compatible scanning devices, but will only be able to connect to one at a time. 

2. You can see this case, for an example on how to implement sensor data in the advertisement. Keep in mind that the advertisement can't consist of more than 31 bytes of data though.

Best regards,

Simon

Now i am able to change the UUID data (16 Bytes) to introduce there the sensor data. Can change other parameters to introduce there data ? 

How can i change the name of the device ? it appears N/A...

On the other hand, i am using timer 2 (interrupt) and timer 1 (pwm) ... when i activate both ... beacon doesnt work. why?

Hi Nasib

I'm sorry, I meant to upload this link https://devzone.nordicsemi.com/f/nordic-q-a/49355/advertising-sensor-data-using-service-data to the last reply (I updated it now), which is a case showing how you can implement sensor data to your advertising. 

You should be able to define the device name using the #define DEVICE_NAME in main.c. This will be included in your advertising data as long as there is room for it. If you have a defined device name and your device appears as N/A when scanning, it means that you don't have room for the device name in your advertising data and it has been "squeezed out" in favor of some other data (likely the UUID you've added).

Best regards,
