A little question about notify

[Ge]

Hi,nordic：

     At this topic: devzone.nordicsemi.com/.../

I know that notify is 100% safe in LL.Before that,i know in bluetooth core4.2 LL has SN and NESN field to guarantee the order and arrival of packets.Now i want to confirm that whether the implementation is the same in Nordic ble stack.on other hand,i want to know that is the answer in the above link is suitable for nordic BLE stack???
My chip is nrf52832,sdk version is 12.3. thank you...

Sure it is. Everyone is using it with all Nordic BLE stacks (Soft Devices) from the day when it was released for nRF51 5-6 years ago.

Hi

As endnode pointed out in the original thread the link layer will ensure correct packet delivery and ordering.

The only way a packet can get lost is if the link is disconnected before the packet has been successfully sent (and if this occurs you will get notified by the disconnected event).

Best regards
