Frequently Asked Questions: Secure Cloud Connectivity and Voice Control Demo for Microchip WFI32-IoT Board
Devices: | PIC32 WFI32E | WFI32 | Trust&Go (ECC608) |
Features: | Secure Cloud connectivity | Voice Control |
The most common issue in this scenario is the firewall configurations of the office network. Cloud connection is done over the secure MQTT port 8883. Many office firewalls block this port. Please talk to the IT department of your office to allow port 8883 in your firewall.
For regulatory compliance, the OOB demo is configured to use RF channels that works worldwide. Since channel 13 is restricted in some countries, it is disabled. Refer to the device software user guide to get information about regulatory domain selection APIs.
The tempertaure reading reported by the board reflects board temperature and not room temperature. Board temperature is relatively high because of high current due to multiple components drawing relatively high current (i.e USB Hub and PKOB4).
When compiled in microMIPS mode and used with MPLAB XC license to enable Os Optimization level, program memory savings of around 20% (201.2 KB) can be observed.
GCC and Linker settings in the Project Properties are highlighted below:
