Looking for some thoughts on where I should go from here.
TX v3.13 Rev B board and RX v 2.00 Rev A both fully assembled and alive.
RX unit is not receiving any data. Boots up and initialises as it should, connects to WiFi and syncs NTP clock etc. I do note that the COM Led is apparently continuously lit. Looking at serial output using the debugging modes, nothing is ever reported beyond "WiFi connection is ON". RX LED never lights. Internal temperature, humidity and barometric pressure are being read from the BME280 with no problems.
The TX board is hooked up to an SHT21 and Davis anemometer + rain collector. Using the debug routines for the TX board I see sane values reported from all the attached instruments. TX LED flashes regularly.
Both TX and RX are set with Station_ID 0xA1, and the TX board has station ID 0. Basically everything other than my specific WiFi and location configurations are at default values or appropriate for the instruments I have used.
As I type, both TX and RX are in the same room with me, with antennae attached.
I am trying to pin down if this is a failure of transmission, reception, or neither. Physically I can see no issues with solder joints on either of the boards. I have reloaded the relevant sketches several times. I have measured voltage across VCC to GND on the TX board module and see 9V. Similarly, for the receiving module on the RX board I see 5V supplied.
I am wondering if I should pull out the 433 Mhz modules and replace one or both, but before going to that length I wanted to see if anyone has suggestions on where to go next.
