Smart Bluetooth Forum Discussions

I'm new to iOS app development / Objective C and I'm trying to add a component to the app underneath the temp / pres / humd bars. This component has to change based on the sensor data but I'm having trouble accessing the component.

I can access the sensor data from classes such as the ViewController, but then I can't change the component because I can't make it as a property in the ViewController.h. I can't create the component as a property in any class other than the GaugeViewController, but then I can't access sensor data from the GaugeViewController.

Any tips on how to go about this?

Thanks

Actually, we have one additional question that goes with the above; When we follow the build instructions the following error message occurs, download failed.this version of SDK only supports download to BCM20736A1 and BCM20737A1 devices...please advise?

Hi,

I downloaded existing SDK sample on multiple BLE sense 20737S, but all of the Ble have same Board address.

How to change and decide board address?

And how to trace? debug?  Eclipse Trace does not works.

thanks

Hi,

Is there any SDK example for demonstrating LE audio using the taG 03 boards?

-MD

I am trying to build this example but it gives me errors. Most of them are common error like "CFA_BSC_STATUS read_status is not resolved". I feel like some library are missing??

Hi,

We are trying to assign unique ID to our modules. OTA update firmware is one way. But because the update is very little change, we are thinking other way to realize it. Then comes out following question:

1. Is it possible create user service and/or modify GATT characteristc for BCM20736? I am not sure the chipset has internal memory for user, although it has the feature that support for EEPROM and serial flash interface.

2. If it is yes for the question without/ with external flash, do you have any doc provide more detailed information?

Thanks!

When I using mybeacon example(in SDK 2.2.1), I got the same issue when I adjust blecm_startAdv()

blecm_startAdv() - advInterval <= 128 not working?

Register the callback function to print some message and check how many times advertisement_packet_transmission() been called before each adv.

bleprofile_notifyAdvPacketTransmissions(&advertisement_packet_transmission, 200);

    // Start advertisements

    blecm_startAdv(

        HCIULP_ADV_NONCONNECTABLE_EVENT,                // non-connectable undirected advertisement

        160,                                            // adv interval 100 msec

        HCIULP_ADV_CHANNEL_MAP_MASK,                    // all channels

        HCIULP_PUBLIC_ADDRESS,                          // int advAdrType,

        HCIULP_ADV_FILTER_POLICY_WHITE_LIST_NOT_USED,  // int advFilterPolicy,

        HCIULP_PUBLIC_ADDRESS,                          // int initiatorAdrType,

        NULL);                                          // UINT8* initiatorAdr

When advInterval=160, it works fine, advertisement_packet_transmission() called 10 times in one second,

but if the value lower than 160, advertisement_packet_transmission() been called only 1 time in one second.

in  ~/include/blecm.h

advInterval The advertisement interval in BT slots (min 32, max 16384).

typo?

Hi guys,

What would be the first steps that I need to follow in order to get an SDK / Evaluation board for the BCM20706?

My understanding is that this is the one already approved by apple homekit.

Thanks in advance!

     as the title！what i mean is  that   i what  to  use  a timer at 2ms  to do ADC receive , but i  can not find how to achieve  it ! is there anyone can help me ?

     also i have find that someone say the timer can not set below 3.5ms , is that ture ?

     thanks
