CC26xx: Multiple writeNoRsp per connection interval?

CM2015

I have some confusion about writeNoRsp. I know that notifications can be queued up such that multiple packets will be sent in a single connection interval. Is the same true for writeNoRsp? Or is it limited to only 1 packet per connection interval?

If it is true, can both notifications and writeNoRsp send multiple packets per connection interval during the same connection interval? Are there any limitations?

Thanks

Hello,

Correct, you can send multiple WriteNoRsp from the Client per connection event. The limitation are the same as Notifications, limited by TX memory, RF conditions, etc.

Thanks JXS that makes perfect sense. Do you know if multiple notifications AND writeNoRsp can be sent in a single connection interval? Sounds like maybe it is possible.

Yes, they can be sent in same CE. Notifications come from the GATT Server, Writes come from the Client.

Oh okay, yeah I understand where they come from but I was just wondering how the stack might receive 2 packets and send 2 packets in the same connection interval (perhaps they're interleaved or something like that). But that doesn't matter too much, as long as it should be possible, thanks!
