Hi all,

i would to know if it is easy to port the code from the SDK1 to the SDK2; if in the SDK2 you have resolved the many bug present in the first SDK and if it is easy to debug using a jlink the code on the SDK 2. Is the documentation about the APIs in the SDK 2 is more exaustive than tne documentation about the SDK 1.Thks.

Hi all,

I need documentation about all of the APIs for the peripheral UART management. Is it possible to get this documentation? Thanks.

Could you tell how to use the api : void leatt_sendErrResponse(INT32 errCode, INT32 reqOpcode, INT32 handleInError ) ( be defined

in the leatt.h)

I don't know errCode, reqOpcode, handleInError ? no any description in leatt.h.

I quess

errCode =

#define LEATT_ERR_CODE_INVALID_HANDLE                      0x01

#define LEATT_ERR_CODE_READ_NOT_PERMITTED                  0x02

...........

reqOpcode =

#define LEATT_OPCODE_ERR_RSP                                 0x1

#define LEATT_OPCODE_EXCHANGE_MTU_REQ                        0x2

.........

but whis is handleInError ??????

In our production need a read gatt character call back function

and a error response.

xxx_create(void)

{

.....

     lel2cap_regConnLessHandler(4, homedoor_l2cap_att_data_handler); /* home_door_l2cap_att_data_handler is l2cap att data access call                                                                                                               back function */

...........

}

static void homedoor_l2cap_att_data_handler(UINT8 *l2capHdr)

{

    uint8 opcode = (LEATT_PDU_HDR*) (l2capHdr + 4);

    UINT16 *handle = (UINT16 *)(l2capHdr + 5);

    UINT8 status = 0;

    switch(opcode)

    {

        case LEATT_OPCODE_READ_REQ:

            status = SystemUtilsReadAttrCB(handle); // is my private GATT sevice and character read call back function

            break;

    }  

    if (status == LEATT_ERR_CODE_NO_ERROR)

    {

        leatt_l2capHandler(l2capHdr); // continue to process GATT service

    }

    else

    {    // status = LEATT_ERR_CODE_REQ_NOT_SUPPORTED

        leatt_sendErrResponse(status , LEATT_OPCODE_READ_REQ,  ??????);                                                                                       }

}

Hi,

  checking from the post Re: 20732 mac filtering possible?, the parameter 'advType' of function belcm_StartAdv can be used for specifying the type 'random'.

  But how do I choose more specific address, ie. static, non-resolvable, resolvable, from this API?

Hello,

has anybody experience in connecting two Tag3-boards via bluetooth.

I am looking for a function which I can use for establishing a bluetooth connection to a certain device. The function "bleprofile_Discoverable(HIGH_UNDIRECTED_DISCOVERABLE, NULL);" seems not the right one.

Best regards,

Christoph

Hi,

  This is the question following Changing BD_ADDR from the application

  Regarding to victorz's description here

You shall not change device bdaddr on every reboot.

  I don't see the same expression from the BT spec as below, which is cited from section 10.8.1 of Part C. of Volume 3.

A device may choose to initialize its static address to a new value after each

power cycle. A device shall not change its static address value once initialized

until the device is power cycled.

Note: If the static address of a device is changed then the address stored in

peer devices will not be valid and the ability to reconnect using the old address

will be lost.

  So, if we need to change the BD address in every reboot, then what would be the limit of write cycle to EEPROM that storing the BD_ADDRESS, in case that we need to write it to '0xFFFFFFFFFFFF' before calling 'blecm_set_static_random_bd_addr'?

I want to change advertisement interval after I call bleprofile_init(bleprofile_p_cfg).

How should I do  ?

How do I set up Eclipse to work with the WICED SDK on Linux?

I have SDK 2.2.0 working just fine on Linux from the commandline, including building and flashing sample apps.  I also have Eclipse ("IDE for C/C++", Luna SR2) working fine (can build Linux native apps for example).  But I am really not sure how to put the two together so as to get an experience similar to the Windows WICED IDE.

Thanks!

I'm sorry if this has been answered before or is somewhere in the docs.

From bleapptimer.h:

// This function will start a fine resolution timer. It should be used with care.

// The timeout is in ms unit.

void bleapptimer_startFineTimer( BLEAPP_TIMER_CB cb, INT16 timeOut);

I noticed a problem with timeOut:

for timeOut = 1000 callback is called about every 12 sec, for timeOut = 100 - every 1 sec.

Is this a bug in bleapptimer_startFineTimer ?

You state that:

GPIOs that are output enabled will remain so and drive as configured in sleep/deep sleep in Sleep Deep_Sleep Explanation and Techniques

We tested this with our BCM20736 device and it looks like it does not work. We set one GPIO as output/high. As soon as the device enters deep sleep the GPIO goes low.

We are using SDK 2.1.1 and the following code snippet taken from etc_sample.c:

When the device is in deep sleep mode then GPIO P3 is low. But it should be high.

Why is this so?
