This is the presentation I gave at Mobile+Web DevCon 2016 about developing mobile application in the landscape of the Internet of Things (IoT). It is a set of best practices around the experience and key learnings that are in addition to the what you normally need to do when developing a mobile application.

1. Mobile Development for Devices and IoT

2. I am going to curse

3. Notorious Liar
Most famous song is about lying

4. Diving In
- (void)peripheral:(CBPeripheral *)peripheral didDiscoverCharacteristicsForService:(CBService *)service error:
(NSError *)error
{
if ([service.UUID isEqual:[CBUUID UUIDWithString:POLARH7_HRM_HEART_RATE_SERVICE_UUID]]) { // 1
for (CBCharacteristic *aChar in service.characteristics)
{
// Request heart rate notifications
if ([aChar.UUID isEqual:[CBUUID
UUIDWithString:POLARH7_HRM_MEASUREMENT_CHARACTERISTIC_UUID]]) { // 2
[self.polarH7HRMPeripheral setNotifyValue:YES forCharacteristic:aChar];
NSLog(@"Found heart rate measurement characteristic");
}
// Request body sensor location
else if ([aChar.UUID isEqual:[CBUUID
UUIDWithString:POLARH7_HRM_BODY_LOCATION_CHARACTERISTIC_UUID]]) { // 3
[self.polarH7HRMPeripheral readValueForCharacteristic:aChar];
NSLog(@"Found body sensor location characteristic");
}
}
}
// Retrieve Device Information Services for the Manufacturer Name
if ([service.UUID isEqual:[CBUUID UUIDWithString:POLARH7_HRM_DEVICE_INFO_SERVICE_UUID]]) { // 4
for (CBCharacteristic *aChar in service.characteristics)
{
if ([aChar.UUID isEqual:[CBUUID
UUIDWithString:POLARH7_HRM_MANUFACTURER_NAME_CHARACTERISTIC_UUID]]) {
[self.polarH7HRMPeripheral readValueForCharacteristic:aChar];
NSLog(@"Found a device manufacturer name characteristic");
}
}
}
}

5. Inter·net of things
noun
noun: Internet of things
1) a proposed development of the Internet in which everyday objects have network
connectivity, allowing them to send and receive data.

6. Numbers
25% of the apps are games
I was going to say more but everyone else
has already put up everything

8. What is Sproutling?
A wearable band for your baby, a smart
charger and a mobile app work together to
not only monitor more effectively but learn
and predict your baby's sleep habits and
optimal sleep conditions

9. Ecosystem
BLE
WiFi
BLE
Sproutling
WiFi or
Cellular
Home
Router
Cloud
Internet Telemetry
Identity
Device Mgmt

10. Experience
Does the user trust your app?
How does your app provide feedback?
Is your app easy to use with the devices?

11. Utilitarian
Setup / Data Entry
Onboarding
Troubleshooting
Customer Support

12. Get Ready
It is all your fault even if it is the device
that messing you up

13. I18N/L10N
Make sure that your app has a great
experience across languages and
cultures

14. Constantly Better
There have been 4 updates since I
purchased my Tesla and it now drives me
to work and I can use my phone to pull
my car of the garage

15. Brand Support
What do you do when your brand has
multiple connected devices?
How does your app compare and work
into the Out of Box Experience (OBE)?

16. Android
Treat android as a first class citizen on par
with your iOS app

17. UV-curing solder mask to home-fabbed boards
Date
“Well you have true pub/sub with MQTT thats the biggest thing. MQTT was built around
the notion of message queuing. Websockets were built from a need for unidirectional http
communication thats at the highest level”
Chris Hein

18. UV-curing solder mask to home-fabbed boards
Date
Battery Life Analysis / Alignment

19. Security
Are you thinking about it?
How do you connect the backend?
How do you connect to the device?
When you interview, make sure you fake
it!

20. Logging
Log all interactions with everything

21. Testing
Integration testing is hard to automate,
take a lot of time and costly to change
Make sure you have great manual tests
and scripts, seriously
Make sure you performance and usability
test!

22. Teams
Hardware and software need to work
together in perfect harmony
Small team communication is easy
Larger teams need protocols and
documentation to avoid running off the
rails

23. Connection
Fatigue
I wanna disconnect myself, do it
I wanna disconnect myself, get it
I wanna pull my brain stem out, do it
I wanna disconnect myself right now

24. Summary
Hopefully you learned a few things and
are excited to start working in IoT
because the robots are coming

25. Thank You
