I just received my wicked sense tag and was able to see the sensor data in my android application. How can I get the data in a mac laptop?

Hello Broadcom,

We are using a 20737S in our product. Is there a way to read protect or write protect the EEPROM that is part of this SiP?

Poring through the datasheets, I couldn't find any indication that this is possible. In fact, it is not clear which EEPROM is being used. The datasheet of the 20737 indicates native support for 3 different EEPROM chips which all support write protection, but no read protection.

Thanks for your help!

When we use Tag3 for test in this mode:

SW3: 3-VREG;

SW2: 3-VCOIN;

Pin31(P15): connect to VCOIN;

VCOIN: 3V.

The battery monitoring in hello_sensor APP is 0;

When use in this mode:

SW3: 3-VCOIN;

SW2: 3-5V_USB;

Pin31(P15): connect to VCOIN;

VCOIN: 3V.

The battery monitoring in hello_sensor APP is 88.

Is Tag3 not use P15 for battery monitoring?

If we want P15 for battery monitoring,How to modify the code?

Hello everybody,

I'm still creating a BLE application on the BCM20736S that is more or less an enhanced UART-bridge from a Cortex-M4 to BLE. The SDK version is 2.2.1.

Receiving data via BLE and sending it on PUART to the Cortex is working flawlessly, the other way round, it is hampered by not sending a notification.

This function fails:

__find_bonded_peer

It is called inside these generated functions:

BOOL store_in_db_*(UINT8* p_value, UINT8 value_len, BOOL write, BOOL notify)

But the iPhone is connected to the BLE module and the connection up callback is executed. A maximum of five peers is allowed.

I'm afraid, that there might be a basic misunderstanding on my side, regarding peers and bonding.

Do I have to actively add a peer on connection up? How to do this?

The use case is, that multiple devices are connected to the BLE module, be it mobile phones or future BLE accessories. But at the moment I'd be glad, if only one device would work...

On the iPhone a cross-platform software built around the Xamarin/MonkeyRobotics toolkit is running.

Using my custom function

static void notificationWithDB(UINT16 handle, unsigned char *data, unsigned char length)
{
    static const unsigned char zeroPad[22] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
    unsigned int i;
    BLEPROFILE_DB_PDU tempPDU;
    if(length > 0)
    {
        i = bleprofile_ReadHandle(handle, &tempPDU);
        if (tempPDU.len > length) //zero padding here
        {
            memcpy(tempPDU.pdu, zeroPad, tempPDU.len);
            memcpy(tempPDU.pdu, data, length);
        } else if (tempPDU.len == length)
        {
            memcpy(tempPDU.pdu, data, length);
        } else //truncate the data
        {
            memcpy(tempPDU.pdu, data, tempPDU.len);
        }
        bleprofile_WriteHandle(handle, &tempPDU);
        if (blecm_getAvailableTxBuffers() > 0)
        {
            bleprofile_sendNotification(handle, data, (INT32) length);
        }
    }
}

a notification is send.

Some of these do not contain any attribute data and crash the iPhone.

Do you spot a bug?

Thanks for your help!

Dear Support,

   Our customer complained that the phone cannot detect iBeacon of WICED , but we use ibeacon.a to generate the beacon.

   Our customer also post the BLE packet for us to reference. First packet is WICED solution. Second is TI solution and work fine.

   Could we generate same ADV packet like TI solution ?

Hi

I have ordered Tag3 board from mouser UK and i did not get USB dongle with evaluation board. I think USB dongle is not included with Tag3 kit , Which one i need to buy for tag3 booard?

Hi

I have made a board where i used CP2105 in order to pragram BCM20737s. Problem is that my board is not detected by my PC it gives the message "One of the USB device connected is not detected by the system due to malfunction. Connect device again or change the device". I have connected the device several time and i have install the CP210x driver but still it gives the same error. I wonder that may be i made a mistake on schematics. I have attached the schematic kindly look into this.

Have you guys made a J-Link cable yet?

As far as custom cable, please clarify if my understanding is correct:

  - The cable doesn't need power, resistors or capacitors - we need to connect 5 wires from the J-Link connector to the board (PWR_VIO, SWDIO, SWDCLK, GND, RESET) and that's it

  - PWR_VIO and GND of the board can be connected to J-Link's pins 1 and 20, respectively
