If user of a device is removed, then when the device connect to internet, the device is orphelin and noone can register it.

It is not possible to fully use IBM IOT as retain message is not working. So there is no other choices than implementing our own mqtt broker.

Move from SDK v2.2 to SDK v3.0
Adapt air software

if one part of mac address starts with a zero, this zero is omitted.
For example 38:2b:78:03:d7:1d is sent as 38:2b:78:3:d7:1d

Implement a debug module which can not only print message on console but also messages as mqtt messages to our broker.
This way, I can monitor the status of each device.

Use Flutter: https://flutter.io/

French standard

• yearly average should not exceed 40ug/m3

• daily average should not exceed 50ug/m3 more than 35 days per year

It should be possible to update air firmware OTA.

When registering a new device, the user provides the SSID and password of the wifi through a web page.
Once provided, the user does not have a feedback if this registration went well.

air-website may be impacted too.

Firmware should be able to decrypt a token hashed with a public key.

Device should send a running/not running status.
When connecting, send a lastWillMessage = "offline", and lastWillRetain = true, and then send a publish message= "online", and retainedFlag = true

Setup MQTT server on IBM cloud
Send pm values to the MQTT server

Currently the reference start date is hard coded and common for all devices.
It should be linked to registration date of device.

Device should know the time with precision to be able to associate the measurements with a time reference.

It may (or may not?) happen that during a registration something is going wrong. In this case, the device may be registered at server side, but not at device side, meaning that the device does not have any token.
A new registration will fail as the device will get already registered and not the token!

Measure rate could be changed by web interface.
Min 1mn
Max 1 hour

This change impact the mqtt connection as we may loose it between two messages.
