In lis3dsh_driver.c, the function GetAccAxesRaw is responsible for reading the accelerometer data. The relevant code is:

buff->AXIS_X = (i16_t)( (valueH << 😎 | valueL )/16;

Why is the value divided by 16? That loses 4 bits of precision!

If this division can be removed, can Cypress please fix this and provide a new signed firmware image? I could compile and flash my own image but my Android app's users won't be able to follow the recovery procedure. A firmware OTA update (signed by a key recognized with the pre-installed image) will work for them.

thanks,

Hi,

exist a strategy to understand if a connection request has failed?

In an our application seems that sometimes the central device performs a connection request but the connection up callback, on the peripheral device, is not invoked.

The central device is a smartphone with Android 5.1 OS. In particular the APP receives the error 133 (GATT_ERROR)

Thanks,

Armando

The product list in the WICED Bluetooth shows only 20732, 36 and 37. What about the smart ready products supported like 20705?

Where do we see the full list of products being supported currently?

Build Hello_client on wiced-2.2 and donwload it to brcm20736 demo board.GN5001 phone install LE HELLO Client.apk to connect demo board, wait 5s, it will auto-disconnect, who knows its reason? thanks.WICED Bluetooth

For BCM20736, we are using Avnet for programming EEPROMs. The application loaded into EEPROM was built with setting DLConfigBD_ADDRBase = "OUI******" where OUI is 3 byte number.

We shared the .hex file with Avnet for programming EEPROM. When this .hex file is put on 10 EEPROMs, will all these 10 units get the same BD_ADDR ?

Specifically my question is

1. At what point in time, random numbers are generated to resolve OUI******. Is it at compile time or runtime?

2. If the resolution happens at compile time, then the .hex file programmed on multiple parts will end up programming the same BD_ADDR on all parts. Is that correct?

3. How do we assign unique BD_ADDR to our parts at production stage ?
