Hello, community,
As of LORA calculator maximum speed that can be achieved is 5kbps using B-L072Z LRWAN1 board. But I'm not able to achieve that speed. I'm attaching a screenshot.
I have increased the no. of frames per minute by changing APP_TX_DUTYCYCLE and frames transmission speed by changing RECEIVE_DELAY1 and RECEIVE_DELAY2 but still I'm able to get a speed of 1.3kbps.
To increase the speed I have set default SF=7 by the default setting of
#define LORAWAN_DEFAULT_DATA_RATE DR_5
with this setting, it gets a speed of 3.2kbps but after 100 frames this DR_5 drops to DR_4( that is SF=8) then after every 30 frames this DR drops, that is SF increases and the speed again drops to 1.3kbps.
At SF(spreading factor) 7 it's sending 100 frames of 253byte register in 20 seconds and I want to set
#define LORAWAN_DEFAULT_DATA_RATE DR_5
after every 100 frames but im not able to set it, after every try, DR drops from 5 to 0.
IS THIS SF DROPPING AFTER PARTICULAR FRAMES ARE SET INTO HARDWARE ONLY?
Looking for help to get that speed of 5kbps.
Thank you for your help.
