some problem with ble connection process

[so easy]

In the right process，like this：

but my program is ：

i lost “Sent Read By Group Type Request, GATT Primary Service Declaration, Handles: 0x0001..0xffff” .

in the wireshark,some service dont be find. But in the nrf_connect i can find all service and the relevant functions are in normal use.

Did I make a mistake?this is my code

Are you talking about the "Received Error Response - Attribute Not Found, Handle 0x000a"?

That's a normal response when there are no more entries in the ATtribute Table during a service discovery. In your case there are no more entries from handle 0xa and onwards. 

[so easy]

hi,haakonsh. i talking about"Sent Read By Group Type Request, GATT Primary Service Declaration". I'm talking about is my program doesn't have that.

[so easy]

i use iphone test,the Android dont has this problem

[haakonsh]

It's a normal response to a service discovery read request when there's no attribute present in the attribute table within the given range of handles that are requested. 

The traces you've marked in red are both working, what exactly are your symptoms?
