nrf5 SDK 14.2.0 cannot be connected by ios

[weizhen]

hi, I am updating the sdk from 12.2.0 to 14.2.0, and using softdevice s132. I get a problem by connecting device using ios devices, but it works fine with android device. do you know what should I do?

I tried that, that works for 12.2.0, but not 14.2.0. and I check the evt id, which returns 0x21  BLE_GAP_OPT_LOCAL_CONN_LATENCY when I connect by using an ios device

Perfectly works for me in 14.2

Sniffer trace using wireshark and the nRF Sniffer, We have noticed odd behaviour with the s140_nrf52840_5.0.0-2.alpha_softdevice.hex which was definitely connected to the BLE_GAP_EVT_DATA_LENGTH_UPDATE_REQUEST specifically on the multi link example . I think you should bump up the softdevice to a newer version (v5.1.0) and verify if this issue still exists.

I update using SDK 15.0.0 with softdevice 6.0.0, and it fixes the problem.
