Multiple notifications in a single connection interval

[Bryan]

I currently have a design that has four characteristics (all strings) in a custom service. Each is less than 20 bytes and I send them out one at a time. i.e. one characteristic per connection interval.

I have read some of the previous posts, such as below, but I still have questions.

1. Power is a big concern for this design. From a power aspect, is there a benefit to creating a single characteristic and then sending them all in one connection interval.

2. I believe this is the case, but need to confirm. Only one unique characteristic type can be sent in a single connection interval. So I could send the same characteristics up to 6 times per connection interval. Correct?

3. How do I tell how many notifications are received per connection using, for example, Master Control Panel? Basically, how to debug it.

4. Where is an S110 example showing how to send multiple notifications per connection?

Regarding #2: I am not aware of any limitation that would prevent you from sending data on multiple characteristics in a single connection interval. You just need to specify the appropriate handle for each characteristic when setting up the hvx parameters for the data.
