Can peripheral adjust anchor point by sending connection patameter update message in S140 SDK?

[zhangkui]

        In my device， I must support HUB(central and peripheral roles) mode. I found it will drop data in weak signal.  and It will be better when be central roles only in the same signal.  And in the S140 SDK spec, Nordic said there will be more collsion to be peripheral roles.

        But according to the BlueTooth spec, the peripheral can also adjust anchor point by sending connection parameter update messages. Please see the attachfile for detail.

1. How many peripherals are you connected to?

2. What is the connection interval used for the links?

3.What value do you have for ble_gap_conn_cfg_t::event_length ?

[zhangkui answer]

1. the HUB  connect 1 peripheral and 1 central.

2. connection interval is 7.5ms

3.event_length is 7.5ms

[zhangkui's supplement]

I know adjust interval and event length may not drop data, But be a HUB or be a central only is different with the same set.

And your S140 spec said be a HUB the data throughput will be half of be central only in the chapter of throughput. is it true?
