CC2541 can't update S120 connection parameters

[bihu]

Hi Guys,

I'm doing a test between CC2541 and Nordic NRF51822. The CC2541 work as a peripheral role. NRF51822 as central role. But CC2541 can update another CC2541 that work as central role.

I didn't see any packet LL_CONNECTION_UPDATE_REQ on sinffer's capture message. Does this problem is a known problem? And any body have a solution?

Thanks!

Both peripheral and central role device are TI CC2541, I call GAPRole_SendUpdateParam on peripheral role device, I can see the LL_CONNECTION_UPDATE_REQUEST. But I can't see the update packet when central device change to NRF51822. How to explain this problem? I also use the latest TI stack.

I will try the S110 stack and try to update the connection interval to find the difference. I will tell you if I found clues.
