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?

hey Mttrinh, have you got any idea what's wrong with my code?

[Mttrinh]

Have you tried testing with different iOS device? iPhones? iPad? Also tried with different iOS versions?

I can't see anything wrong with your code, have you tried increasing/decreasing the connection interval?

[weizhen]

yes, I tried different ios device and tried  increasing/decreasing the connection interval, but none of it works

[weizhen]

could sdk_config cause some issue?

I found when I got the same problem in SDK 12.2.0, it require me to set the mtu things and make it works. but in sdk 14.2.0, I cannot find any mtu settings examples. do you know what kind of settings do I need to do?
