@matthewtole

Which limits?

Martin Norland

@cynorg

if you get to a point where you're flooding AM, you need to get out of that state, otherwise you're just stuck

'watch busy' or w/e

Matthew Tole

@matthewtole

Ah, yeah

Martin Norland

@cynorg

what you don't want to have happen is an appmessage you really want to get through is waiting behind a line of 20 messages that aren't set to retransmit

Matthew Tole

@matthewtole

That’s more of an internal design detail than an API feature

Oh I see

Because if we just send a bunch without waiting for (N)ACK then we could get stuck

Martin Norland

@cynorg

I see messages that you want to retransmit as implicitly more desired than no-retry messages, you want them prioritized

Matthew Tole

@matthewtole

That would depend on the user set priority of the message as well though wouldn’t it?

Martin Norland

@cynorg

assuming we add priority to the MVP

Matthew Tole

@matthewtole

I don’t think we should

Martin Norland

@cynorg

I'd say have the spot for priority in MVP but don't worry about using it just yet, it'll make compatibility easier and prevent folks changing

I can't particularly imagine someone relying on priority to order the messages for them, if they are I feel like that's a mistaken assumption on their part

then internally we can design the queues as we need to when we're ready to tackle priority

but BAM isn't mine, I'll defer to your judgement

Matthew Tole

@matthewtole

Yeah. If all the messages are being sent with retries, they should be sent in the same order anyway.

BAM isn’t mine, it’s ours

Martin Norland

@cynorg

I'll claim some partial ownership once I contribute more than yammering

Matthew Tole

@matthewtole

What’s the thoughts on what you can send through BAM. Do we just use the Pebble Dictionarys?

Martin Norland

@cynorg

I hadn't given any thought to it - were you thinking of having convenience functions for breaking out images and things?

(phone to watch, of course)

Matthew Tole

@matthewtole

Yeah, that would be ideal

For an MVP probably just using dictionaries is fine, since we can always add new functions later on.

Matthew Tole

@matthewtole

We should probably have an equivalent for all of the AppMessage methods. So you can literally just do a find and replace of app_message_ => bam_

Matthew Tole

@matthewtole

@cynorg Do you want to take lead on the C side?

Martin Norland

@cynorg

I could certainly give it a shot, though I've never done any testing within my kludgy Pebble app(s)

Matthew Tole

@matthewtole

I have a unit testing library we can use

Martin Norland

@cynorg

hahaha I just realized that Travis is unit tests and not a person

(looking at the sidebar)

Matthew Tole

@matthewtole

It’s my friend Travis who sits at home all day and runs tests.

Good guy.

Kind of boring.

But decent.

Martin Norland

@cynorg

reliable, at least.

Matthew Tole

@matthewtole

Can be difficult when you first meet him

Martin Norland

@cynorg

so I presume @finebyte gets the Android side of things, and you're going to take JS

Matthew Tole

@matthewtole

Seems like a sensible division of labour

Martin Norland

@cynorg

I'm sitting here trying to decide if we need to set aside any conventions, or if everything underlying things will be just the pure/raw appmessages that users send

Matthew Tole

@matthewtole

We’ll need to come up with a protocol

Martin Norland

@cynorg

like, are we planning on adding any padding or additional options to the payloads

Matthew Tole

@matthewtole

Yeah otherwise how would we do big messages?

Martin Norland

@cynorg

forehead

cynorg @cynorg slaps his forehead

Martin Norland

@cynorg

I'm a little PKJS spoiled with my 2KB

Matthew Tole

@matthewtole

I was thinking that we’d need a few bytes at the beginning of each message:
BAM_VERSION
MESSAGE_ID
SEGMENT_ID
RETRY_COUNT?

Obviously need to keep it as small as possible.
