I am getting the following error when the AQ111 initially loads. 

E (4070) gpio: gpio_set_level(226): GPIO output gpio_num error

Also, the AQ111 reboots the cpu every second refresh of the PMS7003, refer towards the end of the output from the serial port I have attached. Would appear that the reset is triggered by the load error.

Am using Arduino 1.8.19 and libraries supplied.

Any assistance would be appreciated.
