I need to correct myself. The cabled serial output should be available on
the RJ11 connector if an ADM3483 TTL-RS422 converter chip is installed on
the wireless ISS. See this thread on wxforum:
http://www.wxforum.net/index.php?topic=18656 (see also:

That might provide a working solution, if the console port indeed dumps the
data packets (I remembered it does, but right now I'm not entirely sure).
If it does, it should RS422 signaling. I'm not sure if it can be used to
wake up your module without losing the first few data bytes of the 10 for
Maybe hook up to the console connector then. That would upgrade both my
active station and perhaps salvage the old one as well. Does the console
connector provide a buffer for the data stream so that I could just have
the ULP wake up the ESP32, read out the data buffer, write to the SD,

That's also doable, but a LOT of work. Plus the T/H sensor has a
proprietary protocol, so you might need to replace that sensor. Then you
still need to write handlers for rain, wind, solar/UV sensors (if
installed) as they're not interfaced digitally, and light sensors are
analog, require a spe
I'm kinda assumed the whole ISS board was dead but I didn't really dive
into it at the time. I was thinking along the lines of just hooking up each
of the sensors to the esp32 and use the ULP to aggressively sleep the
wifi/bt between LoRa transmissions. The modules I have came with a SD card

That's an interesting idea. You might be able to use the console connector
present on every SIM board to capture the same packets that are sent out on
radio - *if* it's only the original radio that's dead. The only issue is
the power consumption of the ESP32. Whatever ULP mode it has, WiFi will

Now I am thinking of a change in strategy and just putting one of the
ESP32+RFM95W dev boards into the ISS and send the data out directly,
alternating between moderate range LoRa <-> LoRa peers and occasionally to

The radio should be capable on paper, but the RFM9x series is only used for
LoRa in the wild. The main problem is that there's no suitable driver for
these modules for FSK mode. The RFM69 is cheaper for FSK and there are
several FSK/OOK libs to choose from, plus it already has several working

Right now they are using a RFM69 (don't know if they interfacing with a
RPI) to interface with the Davis Vantage Pro 2 ISS, so I don't see why you
can not use a RFM95W. Did you try searching WXforums? Right now I'm
receiving data from my Davis Vantage Pro 2 ISS without any issues using a
