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!

I just have another look in the S120 v2.0.0 APIs. We do have the compability mode for legacy devices. Could you try to use the opt api sd_ble_opt_set() with the compat_mode set to 1.
