4.2. Debug in Production

To test and debug the assembled UL865-N3G V2, we strongly recommend foreseeing test pads on the host PCB, in order to check the connection between the UL865-N3G V2 itself and the application and to test the performance of the module connecting it with an external computer. Depending by the customer application, these pads include, but are not limited to the following signals:

TXD RXD RESET* GND VBATT VBATT_PA TX_AUX RX_AUX

PWRMON

5. Hardware Commands

5.1. Auto-Turning ON the UL865-N3G V2

The UL865-N3G V2 will automatically power on itself when VBATT & VBATT_PA are applied to the module.

V_AUX / PWRMON pin will be at the high logic level and the module can be considered fully operating after 5 seconds.

The following flow chart shows the proper turn on procedure:

NOTE:

The power supply must be applied either at the same time on pins VBATT and VBATT_PA.

NOTE:

To guarantee a correct module’s start-up please check that the Power Supply is with a level >3.22V within 21mS.

NOTE:

In order to prevent a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the UL865-N3G V2 when the module is powered OFF or during an ON/OFF transition.
