In page 10 of 920732TAG00-HWUM100-R.pdf, it tell use that how to boot BCM20732 chipset from ROM. It can recover BCM20732 when it NVRAM is corrupted and be unable to boot up correctly.

If I use BCM20732S module, how can I do that?

I would like to test the proximity profile example for WICED SMART. Please tell me where I can find a client that would work.

I was wondering if I could get a list of all functions sitting in ROM of BCM20732.

Besides some profiles ROM also contains functions (utility functions) that can be used by user application.

Thanks

I am able to use the hellosensor.exe sample code for the PC dongle communicating with WICED SMART. Is it possible to modify the code for the hellosensor.exe that is running in the PC dongle?

Hello Support

I have the document called MMP20732S-TRM102-R which describes how to layout the BCM20732S SiP module on pages 21 and 22.

I think this description is wrong in on page 22 which shows a drawing of the SiP module and the ground traces around the module. I think the drawing itself is showing the layout looking up from the underside of a PCB whereas the labels for side A, B, C & D have been assigned to the drawing as if the viewer is looking down on the top of the package. Therefore, these labels have been assigned to the wrong sides of the SiP module in the drawing.

The reason for this remark is the description shown on page 21 which states that the signal tracks should leave the module between pins 16 to 19, which would be side D in the drawing if the 'white dot' signifies pin 1. Side D is also the side that you want the antenna ground plane to be routed away from the package, so why would you route digital traces out of side D while also tracking out a very sensitive antenna ground plane??

I would prefer a far better drawing of the layout than the one shown on page 22 if possible, one that explicitly shows the traces for each layer for an optimium layout than the crude drawing in the document.

A downloadable file containing Gerber files for the BCM20732S would be far better.

My application would like to enter a long timed sleep, and possibly wake up on an interrupt.  This seems to work OK, but I am trying to figure out if there is a way to learn how much time I spent asleep, so I can adjust my local clock?

The RTC API seems to reset back to 0 when the sleep ends.  Is there any way to get the elapsed time?

Hi,

My customer is checking if there is a more detailed documentation on function call description?

Which function call they can use to write their applications?

Thank you for your support.

Where can I find a datasheets on the BCM 20736 (BLE+ARM+Wireless Charging)  and BCM 4771 (GNSS Satellite Sensors) ?

Thanks for your help

A few questions regarding directed advertisements:

1. In BLE_PROFILE_CFG is .high_direct_adv_interval and .low_direct_adv_interval in units of seconds or slots?

2. When I start undirected advertisements I get a printout to console: "BLE_high_un_adv:timer(0)" and it works.  When I start directed advertisements I get a printout to console: "BLE_high_dir_adv:timer(0,2).  After this there appears to be timer issues; the normal 1s timer and fine timer essentially crash; they greatly slow down and become sporadic.  Has anyone experienced this?

Thanks.
