Studio Bluetooth Forum Discussions

I'm only interested in the CENTRAL side. I noticed that the wiced_bt_gatt_le_connect call has a scan_mode and an is_direct flag. The is_direct flag has a note in the .h file that says that you must set the background connection type to AUTO or SELECTIVE.  So how does this all work?  If I set scan_mode to HIGH_DUTY and background type to AUTO and is_direct = 0 will the central try to connect to all connectable devices? Does it use the white list? Can I use SELECTIVE to implement my own white list? Also, if I specify is_direct = 0 does the wiced_bt_gatt_le_connect call right away?  How do I cancel the background connection operations?

Finally, is there some documentation other than these .h files describing how this stack works?

I'm working with 20706 and WICED studio 6. For our application we need to rely on the timer to track events.

Looking at the API and examples, here are some questions:

1) Functions like wiced_init_timer(), wiced_start_timer() and wiced_stop_timer() all return wiced_result_t, which might not be WICED_SUCCESS. Can they actually fail? Why would they fail? How do I recover from the failure? If any of them fails, I'm left in a very awkward position, and without knowing more, the only logical thing left to do is reset the system...

2) Would starting a timer affect system sleep? Does the type of the timer matter (periodic vs. one-shot, ms vs. s)?

3) Are there any timing constraints on timer callbacks? How long can my callback function run without breaking the system?

Thanks!

We need to place the CYW20706 in Direct Test Mode (DTM) for BLE RF testing with an external protocol analyzer.  How is this done?

Are the host and dev wakeup lines used during firmware download? Are they active high or low? I'm using 20706. Thanks!

Greetings,

I'm currently tring to design my first Bluetooth application in WICED Studio with a CYBT-343026-EVAL board.

I've found a document called "Getting started with Wiced Bluetooth". The following aspects are stated in one of the paragraphs of this same document:

"

The BT Designer feature of the WICED BT SDK IDE helps software developers generate the Bluetooth

Generic Attribute Profile (GATT) databases and initial code for Bluetooth WICED applications.

The BT Designer is initiated by clicking File > New > WICED Bluetooth Designer in the WICED Studio IDE.

Complete information about this tool can be found in the file ‘Developing Custom Applications with BT

Designer’ under the doc folder of WICED Studio.

"

However, after downloading the last version of WICED Studio, I can't seem to find either the 'WICED Bluetooth Designer' feature nor the 'Developing Custom Applications with BT Designer' file anywhere in the SDK.

Could you please tell me how to get access to them?

If you could provide me with any other information regarding how to get started with the development of a bluetooth application in WICED Studio, I would be much appreciated.

Here's the link to the page where I found the mentioned document:

Getting started with BLE in WICED Studio

I also attatch two captures that show the feature and the file are not where this document states.

Thank you in advance.

I saw you answered the following questions(https://community.cypress.com/thread/31902 ).

I have a similar problem.

Can I get a sample of your supplied fully raw mode sample code?

Thank you.

And one more thing: why did hci_raw_spp sample disappear from wiced studio 5.0 recently?

"For others viewing this thread, yes raw mode is supported by the usual transport APIs, but the RX handler must behave differently than the WICED_HCI RX handler (return bytes read instead of SUCCESS, and do not try to free transport buffer). A sample app will be included in future releases to demonstrate the steps necessary.

lye_2922526, We have already addressed your issue internally: I wrote a sample application that fully implements raw mode that was provided to you over email by your FAE. We plan to release this sample app into the SDK in future releases.

To answer (3): a watermark level triggers the callback."

Hi,

I'm using WICED STUDIO 5.2.0

Demo application 'hci_serial_gatt_service' is not connect Samsung Galaxy Note 4.

I tested with 'WICED Smart Explorer' and 'CySmart' in Samsung Galaxy Note 4.

My application must be connected to the Galaxy Note 4 via serial gatt service.

How can I solve this problem.

Please, Help me.
