Learn more about Data Bridge mode on ESPrtk here: Blog: ------------ When the internet connection is unavailable (the NTRIP / MQTT online service is not available), ESPrtk can use its WiFi signal to transmit GNSS data. This is similar to the full MQTT functionality but is offline. The connections auto deployed in both protocols are TCP/UDP with the distance constrained to the WiFi transmit power. ESPrtk will operate stably with a 2500-3000 meters baseline when using external antennas. For LoRa link , ESPrtk support communicate to external LoRa module (SX1276 , SX1277 , SX1278 , SX12769) via SPI port for km range stransmit. Both support real-time data encryption / decryption using AES256. -------------- ESPrtk -High quality RTK positioning solution with low cost ESP32 RTK.
