I want to use external wireless GPS reciever for my mobile phone.
I have NEO M8N GPS receiver connected to an Arduino's UART port. It send NMEA sentences once pert every second (1Hz) After i get a valid NMEA sentence, then i want to send it trough NFR24L on SPI port.
How can i "tunnel" it? I want to send the same NMEA sentence without modification trough SPI, that i get from UART. Is this possible?
I already did it with 433Mhz TTL module. In this case i used simple SerialPasstrough, and its worked fine. But when i used 433Mhz, then there is no secured connection, two 433mhz modul can interference each other. So i need to swith to 2,4 Ghz (NRF24L), but in this case SerialPasstrough not working. (UART to SPI)
