In Node RN2483 (1.01) , the channels 0,1,2 are fixed with 868.1 868.3 and 868.5 Mhz frequencies and apparently cant be changed.These 0,1,2 are also the channels which are required for a join/response request in case of OTAA .
I have to use IN_865_867 band so I have set the 3 compulsory Indian frequencies( 865.0625 , 865.4025 , 865.9850 MHz as specified in the regional parameter documentation ) at channels 3,4 and 5 ( setting the freq , data rate range , duty cycle and enabling the channels ) .
I also have disabled the channels 0,1,2 .
ABP works fine . But for more security I would like to use OTAA.
The problem is that I am unable to join the network using OTAA : it returns no free channel as its response. I think this is because it only accepts channels 0,1 and 2 for its join request so it is not even considering the channels 3,4 and 5 which are ON and thus showing no free channels.
So how do I get my end node to accept these channels as well for the join request so that OTAA activation works?
Really appreciate any HELP .
