Hummm, it might be worth investigating an ESP8266 or ESP32. You'd have to roll your own programs for them, but it shouldn't be too bad. The good news is that they are available for less than $10 (sometimes less than $5).
Here's a GITHUB that I found that uses an ESP-01. Those things are available for a buck. https://github.com/svkatielee/NMEA_WiFi_Bridge
