Hello,
I’m working with a B-L072Z-LRWAN1 Discovery Board and AT_Slave sample code of CubeExpansion_LRWAN_V1.2.0.
I being able to JOIN to a Gateway, but when I try to send a frame to the Gateway with command AT+SEND= ... , the most of trials I get an AT_ERROR even if the equipment is joined.
Also I tried to send each 5 second the same command AT+SEND … and for my surprise, only one of these commands is accepted with “OK�? (and received as well on Gateway) approximate each 150 seconds.
Does anybody why?
Also I tried to deactivate the Duty cycle restriction with AT+DCS=1 with identical result.
The complete sequence is:
AT<CR><LF>
<CR><LF>
OK<CR><LF>
AT+JOIN<CR><LF>
<CR><LF>
OK<CR><LF>
JOINED<LF><CR>
AT+NJS=?<CR><LF>
1<CR><LF>
<CR><LF>
OK<CR><LF>
AT+SEND=02:Hello World<CR><LF>
<CR><LF>
AT_ERROR<CR><LF>
AT+SEND=02:Hello World<CR><LF>
<CR><LF>
AT_ERROR<CR><LF>
AT+SEND=02:Hello World<CR><LF>
<CR><LF>
AT_ERROR<CR><LF>
AT+SEND=02:Hello World<CR><LF>
<CR><LF>
AT_ERROR<CR><LF>
(190�? aprox)
AT+SEND=02:Hello World<CR><LF>
<CR><LF>
OK<CR><LF>
Does any restriction that I forgotten or other parameters that could produce this behavior?
Thank you in advance,
Regards,
Jai
