Issue: devices Join via OTAA and broadcast data regularly but most Uplink packets are not seen
Setup: RPi 4B bullseye, RAK2245 hat, Dragino LDDS75 and LSN50v2 devices, AU915
Server: Chirpstack v3 with TTN
Details:
-
installed several months ago using RPi image (buster), experienced this problem, set aside
-
re-installed now from GitHub repository on clean bullseye, same problem
-
selected Chirpstack, AU915 freq range
-
created device profiles and devices for LDDS75 and LSNS75, incl Device EUIs and App Keys
-
both devices rapidly Join via OTAA
-
both devices transmit every 20 mins but very few of these packets are seen (less than 10%). those that are seen decode correctly and show correct values
-
RSSI is about -50 for both devices in seen packets
-
i’m a newbie to radio (but very familiar with linux/RPi) so be gentle
-
after lots of searching the only clue i have found is a hint that AU915 has a lot more than 8 frequencies but RAK supports up to 8 so maybe devices are using too many different frequencies - i’m ignorant enough to think that’s feasible
cheers
