		53	= 3. How to Upgrade =
		54
		55	== 3.1 Use DAP-Link and Connect to the Device as above photos ==
		56
		57	We need to connect VDD，GND，SWCLK，SWDIO to DAP-Link.
		58
		59	* Connection method：
		60
		61	* GND-GND,
		62
		63	* VDD-3.3V,
		64
		65	* SWCLK-CLK,
		66
		67	* SWDIO-SWD

		75	Download Link: [[PSoCProgrammer3.27.1>>url:https://www.dragino.com/downloads/index.php?dir=tools/]]
		76	)))
		77
		78	(((
		79	And then use PSoCProgrammer to upgrade the firmware (must use this version: PSoCProgrammer3.27.1)
		80	)))

		115	(((
		116	*If you change different LoRa Frequency Bands/Region, you need using AT+FDR command to restore factory data after program success

		119	= 4. Trouble Shooting =
		120
		121	== 4.1 Unable to detect upgrade ==
		122
