Re: Can an XCODE app can change wifi connection on Ipad without user Intervention ?

Thanks, so atleast xcode app can launch setting interface, with wi fi network parameters(SSID, authentication type, certificates etc) preset  to user to switch to new ipad connection ?

Enabling minimum efforts from user.

How do I change connection interval with core bluetooth.

hello, everyone..

 

I'm developing BLE(BT4.0) App with CC2540 and new iPAD.

I know that the keyfob demo(TI supported source) program can change connection interval for iOS.

But

I have some question. It's like below.

 

1. (CC2540 <------> iPAD)

    Could I change connection interval to 20ms(maybe it's min value) in iOS with core bluetooth?

    I couldn't find it anywhere and it was posslible in the keyfob demo source only.

 

2. (iPAD <--------> iPAD)

    if I use two iPAD(one is master, the other one is slave), where I can set connection interval value?

     I don't know  what is default connection interval value in core bluetooth.

   

I read many threads and documents for a while but I didn't get appropriate answer.

 

In apple's document,

-------------------------------------------------------------------------------- -----------------------------

Interval Max * (Slave Latency + 1) ≤ 2 seconds

Interval Min ≥ 20 ms

Interval Min + 20 ms ≤ Interval Max

Slave Latency ≤ 4

connSupervisionTimeout ≤ 6 seconds

Interval Max * (Slave Latency + 1) * 3 < connSupervisionTimeout

-------------------------------------------------------------------------------- -----------------------------

 

above things can be set only slave side like below,

 

In TI source,

-------------------------------------------------------------------------------- -----------------------------

// Minimum connection interval (units of 1.25ms, 80=100ms) if automatic parameter update request is enabled
#define DEFAULT_DESIRED_MIN_CONN_INTERVAL 80

// Maximum connection interval (units of 1.25ms, 800=1000ms) if automatic parameter update request is enabled
#define DEFAULT_DESIRED_MAX_CONN_INTERVAL 800

-------------------------------------------------------------------------------- -----------------------------

is it true?

I want to change it in core bluetooth or iOS App too.

 

please, give me answer...

IPv6 happy eyeballs breaks connection to secure sites

OSX / Safari seems to choose protocol IPv4 or IPv6 based on best network performance (syn-ack roundtrip time ?). What is even worse, the browser toggles protocol within a secure SSL session (e.g. banking). Most sites that contain sensitive information will break the connection for security reasons if the IP address changes.

In my opinion, Safari should give IPv6 a preference, and should only fallback to IPv4 if the connection is really bad. Moreover, the number of switchovers should be limited since it is almost impossible to finish a secure transaction sequence.

 

As most Internet providers do not yet support IPv6, IPv6 enabled networks do so by tunneling, which makes the IPv6 network slightly slower than the IPv4 network. Still I believe we should give IPv6 a preference.

 

Please Apple, dont discourage early IPv6 adopters and correct this behavior. By the way: Chrome on OSX suffers from the same problem.

 

Jan C.

 

One additional note: the IPv6 tunnel is not terminated on my Macs, but on the network vdsl2 gateway device
