Additionally, there are special actions if you press 'menu' button more than 5 times: • 10 times (starting from firmware ver. 2.55, 9 short clicks than 10th long press to protect from accidental execution) – full erase of all settings. WARNING: Use this option for recovery only, if board is not accessible from the GUI or no other ways to make it working. • 8 times – all COM-ports function will be reset to their defaults: parsing of the SimpleBGC serial protocol only. • 12 times – Serial speed will be reset to default value 115200 and all COM-ports function will be reset to their defaults. Use it if you changed the speed, but your wireless module, used for connection to the board, does not support this speed and board becomes not accessible. (starting from firmware version 2.50x)
