Studio Bluetooth Forum Discussions

Hi, experts,

In Wiced Studio 6.x, come code have been made as library, such as fw_upgrade_lib, it will created .a file while compiling your application if your code reference to them.

The application image could be cleaned by 'make clean', but looks like those .a still stand there even doing so. I would like modify some library code and not wipe them out one by one, is there any convenience way to do this job?

Please, could you send me or to attach the datasheet fo CYW89072 ?. I found the CYW89071 datasheet but I didn't find the first one. Thanks.

In light of yesterday's announcement, are you guys going to support Bluetooth Mesh in future versions of WICED SDK 2, and if so, do you have a rough idea when support for it will come out?

Greetings,

Everytime I send a data packet to my module via SPP, I see that it transmits a huge amount of WICED packets to the host.

In this case, the only bytes that are useful for the host are the ones corresponding to the data received via SPP.

Is there any way to prevent the module from transmitting any WICED packet that is not from the SPP group?

Thank you in advance.

Best regards.

I am using a CYBT-343026-EVAL board to connect to many BLE sensors and to read data from them via GATT. My code is based on the example snip/ble/gatt_db. I would like to connect to as many sensors as possible, in the ideal case up to 16 sensors should be connected.

Every sensor sends 100 GATT notifications per second with a small payload. When I am connected to multiple sensors the throughput of some sensors drops below 100 notifications per second, sometimes as low as 25 notifications per second. I have tried to fiddle around with the parameters conn_min_interval and conn_max_interval. See the table below for my results. max_simultaneous_links was set to 8 for these tests.

I suspect that the problem is an overlapping transmit window that causes some notifications to be lost. Reconnecting one sensor (and therefore setting a new transmit window) sometimes fixes the problem. Setting a fixed transmit window length may fix the problem.

I have multiple questions:

• Is there a fixed limit to the number of connections the CYW20706 chip can set up to BLE devices?
• Is there a way to set a fixed transmit window length?
• Do you have any other suggestions which parameters in wiced_bt_cfg_settings_t may affect the number of connected devices?

Hello, I have a little inconvenience with the example project in this link http://www.cypress.com/documentation/software-and-drivers/cysmart-mobile-app

When I launch it on xcode and set up properly the bundleID name, xcode complains about some missing references in all over the project, is it only me?

Im currently using the lastest version of xcode (9.3), Is there a way to fix up this issue?, or can someone give me a full funcitonal version of this project?, thanks
