DPA Menu is implemented at [N] at TR-7xG transceivers. DPA Menu provides uniform and simple device control.
It allows you to perform many useful actions (e.g. bonding, unbonding, factory setting, reset, standby, …). In addition, the menu can be customized and can include user-defined actions. DPA Menu can be activated in any device state.
The DPA Menu is controlled by the default IQRF button connected to the RB4 and active at LOW. The indication is made using a standard red LED at RA2 active at HIGH.
The DPA menu is activated by pressing the default IQRF button. Please note that there may be a delay before the menu is activated as the device may be in the middle of a time-consuming activity (routing, FRC, discovery, ...). Each menu always contains 9 items. As long as the button is pressed, the menu items scroll. Each implemented menu item is indicated by a single blink of the red LED. Unimplemented menu items are indicated by two flashes of the red LED. The time between menu items is 2 seconds. If the end of the menu is reached and the button remains pressed, three red LED flashes are indicated every 2 seconds.
The menu item is selected by releasing the IQRF button within 1 second after the menu item is indicated (by a single blink of the red LED). Some menu items require confirmation. In this case, the red LED will illuminate for 1 second after the menu item is selected. During this time, the IQRF button must be pressed again. The red LED will then remain lit for 1 second. To confirm the selection of an item, you must release the IQRF button within 1 second after the red LED goes off.
When the menu item is successfully selected, the result will be displayed. The OK result is indicated by the red LED lighting up for 0.5 seconds. In the event of an error, rapid flashing of the red LED is indicated. In addition, some menu items indicate more detailed information by the further flashing of the red LED.
The following diagrams explain menu navigation and an indication of the result. In the example, the 1st and Nth menu items are implemented and the 2nd menu item is not implemented.
