638
639
640 == 7.2 How to change the LoRa Frequency Bands/Region? ==
641
642
643 If user has for example US915 frequency and want to change it to AS923 frequency. User can follow the introduction for [[how to upgrade image>>||anchor="H7.1Howtoupgradetheimage3F"]]. When download the images, choose the required image file for download.

646 == 7.3 Can I disable uplink for each event to save battery life? ==
647
648
649 Yes, User can use below method to disable this:
650
651
652 (% style="color:blue" %)**via AT Command**:
653
654 (% style="color:red" %)**AT+DISALARM=1**(%%), End node will only send packet in TDC time.
655
656 (% style="color:red" %)**AT+DISALARM=0**(%%), End node will send packet in TDC time or status change for door sensor. 
657
658

666 == 7.4 How to change Sub-Band for LDS02? ==
667
668
669 (% style="color:blue" %)**Before v1.6 firmware**(%%): LDS02 works in Subband 2 by default in AU915 / US915 band. So if the LoRaWAN server works in other subband, there will be issue for LDS02 to Join the server. In this case, User can use AT COmmand to change the subband. See AT Command chapther for the hardware connection. Below are the steps to change sub-band:
670
671 * Press rest button.
672 * Send (% style="color:blue" %)**123456**(%%) password
673 * Send command (% style="color:blue" %)**AT+CFREQBANDMASK=0006 **(%%)( 0001 for subband 1, 0002 for subband 2, etc..)
674 * Press rest button to restart to new subband
675 * Example output:
