Hi! Everyone!

I first meet the WICED last month. but I confused many thing ^^.

Our target device need to advertising. So We connect to target device using cellphone.

and cellphone will control our device to scan other bluetooth devices.

So. I think that both roles (central & peripheral) will be needed.

How can I do this?

Thank you!

Sincerly!

Hello,

I'd like to use BCM920737 as a SPI slave configuration, following the example at apps/spi_comm_slave I can send and receive data.

However I have a question : when the chip has nothing to send and therefore TX fifo is empty, what gets sent over the MISO line ? is there any hardware guarantee of a well defined value ? usually other SPI hardware that I've used before guarantee that when a FIFO is empty the value 0x00 is sent. what is the case with BCM920737 ?

running apps/spi_comm_slave code as is and using a generic SPI master I can see garbage sent out on the MISO line when I didn't explicitly set something in the FIFO ? can you confirm that ?

using SDK ver. 2.2

Thanks,

Hi Guys,

I'n just wondering is this possible that connect the wiced sense to android phone and getting all the data value from sensor. Then push all the data to Arduino? or connect wiced sense direct on Arduino?

Thanks,

Per this thread here: Measuring Battery life with BCM20732S​

I am in a very similar boat to the original poster.

I have a battery that can vary in voltage from 2.8 to 4.2v.

For this reason I have a 2.8v (output) regulator connected between my battery and the VBAT pin of my bcm20737s.

When I turn on my module and view the battery percentage, it is always roughly 66%.

What I intend on adding to the next revision if my board is the following circuit:

Supply is connected to my battery (2.8 to 4.2v)

BATT is connected to P8 (ADC)

BATT control is connected to P24 (GPIO)

As my bcm20737s is running at 2.8v passing straight in my battery voltage to P8 would be very harmful as it is above the recommended input voltage. Also it would be larger then my adc voltage reference.

So I have set up a voltage divider law (2K2 & 1K1) which when my battery is at 4.2v, P8 will see 2.8v.

As there is a voltage divider according, and I left my module sitting on a shelf for a long time my battery would eventually run dead.

So I have included a npn transistor. The transistor is controlling the ground path of the voltage divider.

If I apply voltage to the base of the transistor my voltage divider will be connected to ground and the flow of electricity can occur.

if I do not apply voltage on the base of my transistor my voltage divider will not be connected to ground and the flow of electricity cannot occur.

This same theory can be applied to improve power consumption while the module is running.

I know I will have to pass the voltage of P8 to the function that is calculating the battery voltage currently.

I also know I will have to change a few parameters for the calculation to be correct.

Can anyone see any problem with the above design?

How will I pass the voltage of P8 to the current battery calculator?

Thanks,

Luke.

Hello,

  We have a critical roadblock to getting a product to production due to power consumption.  It has been found that the issue is the devlpm_registerForLowPowerQueries() works upon out of the box after a fresh 'Programming' of the device but after the Device has gone into DEEP SLEEP and awakes from DEEP SLEEP the callback function that is defined in the devlpm_registerForLowPowerQueries() no longer gets called to allow the device to go into IDLE/SLEEP mode.  I have attached both a BLE_TRACE output where you can see the callback function getting called before going into DEEP_SLEEP and then after the Device wakes up the callback function to check to allow the device to go into IDLE/SLEEP is no longer called even through the same devlpm_init() and devlpm_registerForLowPowerQueries() gets called?

Hi,

Is there any way to disconnect ble actively from hardware? Currently using BCM20737S. Thanks!

Best regards,

Hello Dear All

I am new at here. I have wiced sense kit.

I allready dowload the Wiced Sense firmware 1.1 to understand how the kit is working

I download sdk 2.1.1 as I read from Wiced Sense Kit Blog and watched the all videos.

My problem is when I open an application listed below in SDK2.1.1 and when I open .c files I saw lots off could not be resolved eror.

Even when I watched the other videos I saw that also in that videos the problem was same . But nobody mention about thesee erors.

Please help me

Regards...

Hi,

We have a concern to add unique MAC address into BCM20726 Bluetooth chip. As of now we are adding MAC ID into the firmware using "AlterIntelHex.exe". I don't know whether this "AlterIntelHex.exe" has provided by Broadcom or some other third party. Can some one guide me how to flash the MAC ID into the BCM20726 BLE chip using right method? Thanks in advance.
