I purchased two Grove Wio-E5 (113020091).
One unit connects and allows me to send messages no problem.
The other unit will only allow me to send one message after joining the network.
This unit changes the channel number after the message is sent. If I change the channel number back then I can send one more message.
Here is the tests that I did on both units:
AT+RESET
AT+FDEFAULT
AT+DR=US915
AT+DR=3
AT+CH=NUM,8-15
AT+KEY=APPKEY,""
AT+MODE=LWOTAA
AT+CMSGHEX=“0102030405060708”
after that message is sent this is the channel numbers:
+CH: 8; 0,902300000,DR0,DR3; 1,902500000,DR0,DR3; 2,902700000,DR0,DR3; 3,902900000,DR0,DR3; 4,903100000,DR0,DR3; 5,903300000,DR0,DR3; 6,903500000
,DR0,DR3; 7,903700000,DR0,DR3;
I change them back to this:
AT+CH=NUM,8-15
+CH: 8; 8,903900000,DR0,DR3; 9,904100000,DR0,DR3; 10,904300000,DR0,DR3; 11,904500000,DR0,DR3; 12,904700000,DR0,DR3; 13,904900000,DR0,DR3; 14,9051
00000,DR0,DR3; 15,905300000,DR0,DR3;
I can then send another message which changes the channel numbers again.
What function is doing this?
