The following are now part of a separate repo (and included as git submodule):
- MQTT glue layer
- Work Queue
- Utilities (reset, reboot, time sync, timezone, etc.)
- Factory Storage
Even CLI is now a part of a seperate repo, included here as a git submodule.
- In claiming, change the 4 byte random number to 64 byte and store it
as binary data instead of hex representation.
- Instead of reading PoP as hex string from NVS, read it as binary data
(because of above change) and then convert to hex representation.
- Instead of using mac address, use last 3 bytes of the above random number
number as suffix for SSID.
The last change was made so as to allow generating the QR code completely outside
the device, without knowing its mac address.
Earlier, it was the application code's responsibility to call the
esp_rmaker_user_mapping_endpoint_create() and esp_rmaker_user_mapping_endpoint_register()
APIs at appropriate places in Wi-Fi provisioning code to enable user node mapping
functionality. To simplify this, the logic has been moved to RainMaker Core, so that
this happens automatically.
For some reason, if you want to retain the older logic in your application code
and do not want RainMaker_core to enable this, please set the
CONFIG_ESP_RMAKER_DISABLE_USER_MAPPING_PROV config option.
If IDF version being used is 4.0, following changes will happen:
- tcpip_adapter will be used, instead of esp_netif.
- MQTT port 8883 will be used, even if 443 is chosen, because
443 requires ALPN options in MQTT, which aren't supported in IDF 4.0
MAC address is a public information and can also be sniffed easily. Creating the proof of
possession pin from that is not secure enough. Instead, a random stream of bytes is now generated
and stored in the fctry partition during claiming and that is used for the PoP.
