A : device 1
B : device 2
C : phone
A and B is pair
A is connected and pairing with phone C.
at time
i wanna let A to scan other device(B) and connect B.
But on same time, both pairing and scanning seems to cause big overhead.
It somtimes raise BLE connection down.
I try to low 'high_scan_interval', 'high_scan_window', but it's no use.
how to can i somoothly scan and connecting to other device, during on paring?
Show LessHi,
I am trying to access(read/write) the data section of the SPI FLASH (Not only SS) for a custom OTA development. Our ultimate requirement is have our own OTA mechanism with an access (read/write) to the upper 64KB of flash memory. Can any body suggest the APIs to access the SPI flash memory of 128Kbytes. Is there any APIs with which we can read/write a SPI flash memory by mentioning the read/write address with the size as arguments.
Thanks and regards

SDK: 2.2.1
Tag: 920737.
app: hello-sensor based APP firmware.
OTA firmware size ~ 18KB.

Description:
Our device meet a problem that we implement a power deep sleep mechanism and then
push button to power-on it again. But at next wake-up, it still goes power-on hello_create() init procedure.
However, we measurement the power-on time to see LCM power-on icon is too slow, approximately near
3 sec.
Does new SDK solve this problem or any other approach to solve this problem?
Show LessHi all,
Current we are using the Serial flash with BCM20737. After reviewing the page http://community.broadcom.com/community/wiced-smart/wiced-smart-forums/blog/2014/06/22/memory-map-explanation#comment-3251 .
We have some question below:
1. Since we are using SFlash, the NV should be 4k-bit area, what is the purpose for 2 area? For OTA only? (VS1 and VS2)
2. The SFlash only guarantee the 100K rewrite ability, is there any garbage collection in the ROM code? Say, if we write an 1-byte NV item every 5 seconds. Does the byte become broken after 6 days?( 5*100000 / (60*60*24) = 5.787)
3. If the byte become broken, does the ROM code have the bad-block check ability in NV area?
Thanks.

Hi, I am a freshman in this field of WICED sense DESIGN.When I prepare to install the WICED-Smart-SDK-2.1.1-IDE-Installer, it always show me this photo followed:
Can you tell me what is the problem? thanks!
Show LessHello,
I need to do a "Find by type value Request" ATT routine as defined in the standard Vol 3, Part F, Section 3.4.3.3, according to the headers the API legattdb_findByTypeValue should do that, however when I use it I get no response and I can see on the sniffer that nothing is actually sent. there is a good chance that I'm using the API incorrectly since I couldn't find any examples.
Do you have any examples using this particular API, I'm aware of other discovery procedures mentioned in the automation_io_client example but since I'm interested in only one particular value I need to use this API
Thanks,

how to do remove the Tx power level from the adv payload?
Show LessWhat is there function like a "delay" in WICED Smart SDK?
I am a Japanese student.
I would like to blink LED to use like a "delay" function.
But I couldn't find it.
Please tell me.
Show LessHi
I tried to connemct wifi module on 20737 ble sense (sensor, keyfob) thru SCL SDA. but have some questions
1. how to integrate wifi library? ( seems like it already has internal 10k pullup register, please confirm)
2. is it possible to send scanning data ( as observer mode) thru Wifi, can somebody direct me an example?
3. Can config Peripheral (for configuration reason) + Observer mode?
Thanks
