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.

Hi,

I found it will drop data in weak signal. 

How did you detect/measure this? Note that if the signal is weak, and/or there are RF interference, some packet might be retransmitted.

I must support HUB(central and peripheral roles) mode

So the HUB is acting as peripheral, connected to another central. And is also acting as central, connected to 1 or more peripherals. How many peripherals are you connected to? What is the connection interval used for the links? What value do you have for ble_gap_conn_cfg_t::event_length ?

Can you have a feedback?
