Smart Bluetooth Forum Discussions

Hi, 

I'm new to this IoT, & i would like to test RF parameters of "CYW20719" Bluetooth device,  kindly help me to get the AT commands to keep device in manual mode for conducting the Tx, Rx tests.

Hello,

when going through the docs, i noted BlueTool utility, and BTSP Perl module.

But i couldn't find download links for those.

Can you point me where can I find the tools?

Thx.

Hi all

I'm trying to implement my own C code to program BCM20737s through UART port.

I've generated my appication with WICED Smart IDE that I've tested downloading it  .

Now I'm trying to program BCM20737s from the micro of my custom board through UART port.

To do that I'm implementing the C code following the procedure specified inside WICED HCI UART Control Protocol documentation.

I've been able to execute every step described in the document until download minidriver procedure the deviced stopped sending response to ther commands.

If I try to start the procedure again now the device send a response only for reset command and if I try to download the application with WICED Smart IDE now the download fail with the following message:

     Downloading application...

     ****Download failed - Press the reset button on the device and retry ****

Can any one tell me why now BCM20737s seems to not work any more?

What I have to do to recover the situation?

Thanks a lot

Hi,

I'm looking for the procedure to udpate FW of CYBT-343026 from Host CPU and OTA.

Q1: Is there any good document and sample source code to update FW from Host CPU.

I think HCI UART under programming mode could be used by we are not sure host CPU control side.

Q2: Does CYBT module support OTA FW update?

       If so , is there any sample application and smartphone application?

Thank you.

Hello,

I'm developing a device run on coin cell battery with CYW20737S.

I've managed to set lowest TX power -20dBm, advertisement interval: high 100ms for 5 sec, low 640ms for 5 sec.

Now I would like to estimate battery life based on these settings. I read the datasheet but haven't found any clue on how current consumption related to TX Power level (?).

The only parameters mentioned in the document is below table, which is general without a specific condition of radio TX power.

Could you please help provide with more detail on current consumption of the device during advertisement?

Thank you in advance.

Best,

JS

CYW20736S Please explain the low power modes. Would like to run the BLE radio in low power maintaining a link as described in AN92584.

Hi cypress

    Can I use cyw20737 to develop mesh application ?
