Smart Bluetooth

Hi,

I'm trying to install WICED Smart SDK on my Mac which is at 10.15.7 Catalina. However, I can't install the current 2.2.2 version. When I try to open the installer I get this message: 

"The application “WICED-Smart-SDK-2.2.2-IDE-Installer” can’t be opened."

I tried an older archive version - 2.0.1. This time the installer opened, but then I got this message when trying to install:

"This package is incompatible with this version of macOS. The package is trying to install content to the system volume. Contact the software manufacturer for assistance."

Does anyone know how to fix this or if this SDK can be installed on macOS Catalina? Any help would be appreciated.

Thanks!

I'm working on a BLE project which has one output data service with three characteristics in it (that correspond to the three data channels I need to send). I'm sending all this data using notifications.

For some reason when I use any of the iOS BLE apps (For example in the screenshot below I have the nRF Connect App for iOS) I cannot see all the characteristics. I can see one of them but I still can't enable the notifications even for that one characteristic. (this happens with the Cysmart app, LightBlue iOS apps as well).

The weird thing about this is that when I use the Android counterparts of the same apps, I don't have this problem. I can see all the characteristics and I can even enable the notifications for them.

Is there anything I can do here to fix this issue with the iOS 

This is how my characteristic definitions look like (I can share the code text itself just let me know)

Hello, first off thanks to all team for all the detailed documentation and support.

I have setup a CYBT-353027 module as an audio sink, sending I2S signals to a codec. All code from your repos and using Modus Tool Box. The codec is setup as the I2S master with a sample rate of 48KHz.  BT modue set as I2S slave by setting the is_master flag to false as per KBA228409. Probing the BCLK, LRCLK and DATA with a scope reveals all signals to be seemingly in order, with the codec driving the BT Module at the right BCLK and LRCLK, and DATA being returned by the Module. However upon hearing the audio playback I can notice the amplitude oscillating quite vigorously, at about a rate of 1Hz. To isolate the issue from the codec I proceeded to stream a pure sine wave of 175Hz from my android phone and decoded the i2s packets. The resulting playback is the same, so my attention turned back to the BT module. (data capture attached). My hypotheses and associated questions so far are the following:

1-Could this be aliasing due to mismatch in sample rate? I noticed the A2DP only negotiates a sample rate of 44.1KHz with my android phone and I haven't found a way to force it to 48Khz from the phone. How does the module deal with this scenario in this case, given that its an I2S slave driven at 48KHz, but the BT is fixed at 44.1KHz?

2-Could this have anything to do with the BT Codec used?

Thanks in advance for your insight.

HI,

        I bought a CYBLE-013025-EVAL , and it includes CYW20737 silicon device .  I saw the datasheet of CYW20737  mentioned it supports "Bluetooth Smart Audio", and details can  available in application notes on this topic. However, I can't find related application notes  introduce how to implement this function by SDK(WICED SMART). Does there has application notes about how to implement Bluetooth Smart Audio?

Thanks

Best regards
