I am using BCM20737s and would like to send my device ADV visible for all devices, but could only connect to the specific set of central devices.

is this possible?

I have a new Problem with my application:

Sometimes my application (handset) can't receive advertisments from my sensors.

For further tests I set up a second sensor.

But if my handset is connected to one sensor, there is no callback of advertisements of my second sensor, but with a smartphone I can see the second sensor is still advertising.

Anybody a hint what I forgot to call so my handset can connect to more than one sensor?

Hi to all

When BCM20736S/37S will have a support for BLE 4.2. and what will

be the data throughput possible ?

Thanks

I am running a simple application on the BCM20736S, and I am hoping for a fast startup. I am not using BLE at all in my application for  now. It is a long story, but for the moment I am just using the fast timer callback, I2C, PUART and a some simple logic in the code.

My problem is that I see slow and inconsistent operation of the fast timer callback, especially at startup. It gets called a few times a second, sometimes once every few seconds. The rate is currently set to 10ms, which should give me 80Hz call rate for the best case. Here is my debug output where I simply print a counter value from the fast timer interrupt.

Hours:Minutes:Seconds - Counter

15:30:49 - 29

15:30:49 - 30

15:30:49 - 31

15:30:49 - 32

15:30:50 - 33

15:30:53 - 34

15:30:53 - 35

15:30:54 - 36

15:30:54 - 37

15:30:54 - 38

15:30:55 - 39

15:30:55 - 40

15:30:55 - 41

15:31:08 - 42

After I run for awhile, this slow behavior will sometimes go away, and sometimes not. When it is working well, I see a consistent 80Hz rate of timer callbacks. I am hoping for this behavior all the time.

My questions are:

1. Is there a way to turn off the BLE tasks (or other processor hungry tasks) that are keeping the fast timer callback from running? I have a simple application, so do not need BLE at this point.

2. Is this normal behavior for this part? Is there a way to improve it?

Thanks in advance,

I am trying to communicate to BCM20737 tag board with peripheral uart. I followed the puart functionality from puart_contorl example

Also what I send to terminal using puart_print/puart_write is displaying correctly. So I think the setup is correct.

The problem I see is what ever value I receive from puart_read is not same as value I send from terminal, please let me know what can be the reason for this behavior.

FYI : I have set the same baud rate on PC and BCM20737

Thanks

Hi Sir ,

I want use MCU Control Bcm2073X Kit through UART ,

sample app tx rx pin is

GPIO_PIN_UART_TX  32 ,

GPIO_PIN_UART_RX  33 ,

Can tell me Where Tx,Rx , Power , GND Pin  on 2073X kit ?

Thanks you !

Per this thread: Application Button in WICED Sense Smart Tag

Has anyone made any progress towards exposing the button status to connected applications?

Thanks.

As I understand, when android request 'pairing', connup_callback and conndown_callback are called sequentially.

next, when android request 'connection', connup_callback is called.

is that right?

if so, can i know whether this event is paring or connection  in connup_callback?
