How to change the downlink window open time
I am using firmware version 220.127.116.11
When waiting for a confirmation of a "at+send=1,1,XXXXXX" , it takes around 40 seconds to get "at+recv=6,0,0" when the message fails.
I would like to make that time much shorter because after 5 seconds of having sent the message it never receives a "at+recv=1,0,0". In other words, the confirmation always occurs in the first 5 sec.
@FerCossio Because you send data as need confirmed uplink, so if gateway did not response the data, the lorawan protocal need macretry the frame, retry times default as 8. you can use follow commad set at least 1 .
