Your suggestion of an attachable device is totally fine, actually very good idea. So, this SDR device would be the medium to the software radio (app in the mobile phone), which controls the device. How would this scenario be possible to achieve the goal? Goal is to send (GPS) data over the radio frequencies to update the app's map. :) _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
