This library allows an Arduino MKR NB 1500 to set, connect, and publish data to an MQTT broker utilizing u-blox SARA-R4 series AT command set.
It serves as an extension, and relies on the MKRNB library for its functionality.
It is tested on the SARA-R410M-02B loaded with the firmware:
- Modem: L0.0.00.00.05.12
- Application: A.02.21
Note: According to the firmware's known limitations, MQTTS does not function properly [u-blox id 3869].
