Ah yes…My bad it is an output on the GPS…
so I am trying to map I/O within lora_pkt_fwd application for an RPi5. I cannot seem to find schematics for WM1302 or WM1302 Pi Hat. My lora_pkt_fwd that I currently downloaded off of github is
SX1302_RESET_PIN=23 # SX1302 reset
SX1302_POWER_EN_PIN=18 # SX1302 power enable
SX1261_RESET_PIN=22 # SX1261 reset (LBT / Spectral Scan)
AD5338R_RESET_PIN=13 # AD5338R reset (full-duplex CN490 reference design)
The wiki for the WM1302 and Pi Hat don’t even mention SX1302 in pin naming…
WM1302
pi hat
Basically I am running somwhat blind here as I would like to confirm what the 4 pins above should map to an RPi5 AND to boot I would like to know what pin maps to 1PPS on RPi5?
I have seen code changes re-mapping the above to 17, 18, 5 and 13 respectively but once again I cannot validate this for RPi5.
For what it is worth I am connected to a network server and appear to be working EXCEPT my GPS timestamp as it continually shows a static stamp of year 1999
Just bcz my lora_pkt_fwd and reset_lgw.sh run doesn’t give me any confidence that it correctly is setting the right gpios for reset
