Smart Bluetooth Forum Discussions

I made a couple of very simple custom boards that host the BCM20732S SiP.

I can successfully download the firmware onto the module and connect to it. However if I disconnect and try again, the peripheral cannot be discovered anymore.

1 - I use LightBlue app to scan and connect to the peripheral.

2 - I tired this with other sample firmwares that same with the SDK and the same things happened. Confirming that this has nothing to do with my own firmware.

3 - The interesting thing is that I do not have any issue with the BCM20732 TAG dev kit. I can connect and disconnect as many times as I want to the peripheral but when I run the same code on the module, the module becomes undiscovered after 1 or 2 times of connecting to it. Depending on how much time I allow before I disconnect and reconnect, I can only reconnect only once or twice before the module become undiscoverable (stops advertising).

4 - At first I though the problem might be because of lack external pull-up/down resistors on RESET, TMC, SDA, SCL pins (I assumed they are probably picking up noise). Then I tired soldering pull-up/down resistors to these pins through test pad on my board, but the issue persists.

5 - I barely have anything else on the board and this is driving me nuts. I can share the schematic through email (since I cannot attach pictures here)

Please help!

Thanks,

If you have the datasheet of BCM20706,Pls email to baofeng@compassic.com.TKS!

Hi All,

I've been able to add a sample BLE application in the WICED-Smart-SDK-2.2.2/WICED-Smart-SDK apps directory, build and deploy it to hardware, but I'd like to have my application source outside of the SDK's install directory.  In order to use the SDK's toolchain, I tried adding -I's to my Makefile based on absolute paths under the SDK install dir, which helped gcc find headers, but I still have undefined symbols like "UINT8" etc. despite including types.h.

Adding VERBOSE=1 to the sample app target I built show that make is using the "spar" directory with:

"Tools/common/Win32/make.exe" -C Wiced-Smart/spar   -j4  cgs

Are there other examples of adding an app outside of the SDK tree, or guides on how the "spar" make system works?

Thanks!,

John

Hi,

Info:

SDK 2.2

BCM20736S

In my application's create function I now call "wdog_configure(FALSE);" because I don't want to use it anymore.

But I still get watchdog resets, I think.

Then I noticed that I forgot to remove the "wdog_restart();" call from the code.

So my questions is:

Does the "wdog_restart();" call re-enables the Watchdog?  Apparently it does.  Can anyone confirm?

Thanks,

Gil

Hi,

in my project I tried to integrate the secure OTA update functionality following the document "WICED-Secure-Over-The-Air-Firmware-Upgrade.pdf".

I'm using the Android App "Smart OTA". It works fine with the "wiced_sense" project on my device,

but using my project on my device I could never connect with this App, so I can not start an upgrade or even read the version info.

My device is based on the BCM20737S and I'm working with the WICED SDK 2.2.2.

Without the opportunity of debugging the App and debugging my device it is not possible to solve the problem, before start the production next week I urgently need help!

1) Does the recovery procedure mean the original application is installed or just that it is put in a state to accept new firmware?

I have done the recovery procedure on two sensors because I was having trouble downloading firmware in general and after the IDE claimed success, neither appear to start up via the battery or do anything at all (no LED activity, do not appear in the iOS test app anymore)

2) What is the magic sauce  in pushing the reset button to download firmware?

Even though I know I have the UART correct because the recovery claims to succeed, I can not get anything to download.  It always says to press restart.  I have the board removed and connected via the USB cable, same as for recovery.  I have pressed it, held it, done the combination with the boot button like for recovery, done other combinations with the boot button, held while inserting the usb cable and pretty much every variation I can think of without success using

WICED_SENSE-BCM920737TAG_Q32 download UART=COM7

or similar for other examples I have tried.

I am using wicked sense tag and wicked smart sdk 2.2.1 to flash code into it. I am able to download and build the wicked_sense inbuilt app on my tag but not able to debug it. While dubugging I am getting an error that "Error in final launch sequence". can you help me out of this?
