8.14 RXWIN2
Set second RX window frequency and Data Rate. This command will change RXWIN2 configuration,
which may cause downlink lost, if configuration is wrong.
Format:
AT+RXWIN2=Frequency,DRx
// Set frequency and datarate
AT+RXWIN2=Frequency,SFx,BW
// Set RXWIN2 through SF and BW
AT+ RXWIN2=?
// Query RX Window2 configuration
AT+ RXWIN2?
// Query RX Window2 configuration
AT+ RXWIN2
// Query RX Window2 configuration
eg: AT+RXWIN2=433.3,DR3
// Set RXWIN2 433.3MHz/DR3
eg: AT+RXWIN2=433.3,SF7,500
// Set RXWIN2 433.3MHz/SF7/BW500KHz
Return:
// General data rate
+RXWIN2: 433300000,DR5
// Customized RX Window2 data rate with spread factor and band width
+RXWIN2: 433000000,SF7,BW125K
From firmware 1.8.0, RXWIN2 command could support more flexible configuration. Both LoRaWAN
defined data rate (combination of spread faction and band width) and LoRa defined spread factor and
band width format are supported. User could set his RXWIN2 to any possible SF and BW scheme,
which is a very useful function for LoRaWAN proof of concept.
8.15 RXWIN1
RXWIN1 command could be used to set customized RXWIN channel, each RXWIN channel maps to
an uplink channel. When RXWIN1 is enabled, user need make sure every uplink channel has its own
mapped RXWIN1 channel, or the modem may perform unexpected.
With this special RXWIN1 command, a function of frequency shift between uplink and downlink
is possible, then full-duplex is easy to achieve for the system if gateway support.
a) Enable RXWIN1
AT+RXWIN1=ON
b) Disable RXWIN1
AT+RXWIN1=OFF
c) Set RXWIN1
AT+RXWIN1=CH,FREQ
CH is the channel number 0~16. FREQ is in MHz
eg: AT+RXWIN1=0,868.9
d) Check RXWIN1
AT+RXWIN1
// return normal or special case
// RXWIN1 is disabled
+RXWIN1: OFF
// RXWIN1 is enabled
+RXWIN1: ON; 8; 0, 923300000; 1, 923900000; 2, 924500000; 3, 925100000;
+RXWIN1: OFF
// RXWIN1 is enabled
+RXWIN1: ON; 8; 0, 923300000; 1, 923900000; 2, 924500000; 3, 925100000;
4, 925700000; 5, 926300000; 6, 926900000; 7, 927500000;
