@@HaseebElectronics I have RYLR998, when set band using At command "AT+BAND=865000000", it remember only when it is connected, when i disconnect and connect and ise "AT+BAND?" it shows +BAND=915000000Hz, why it is not remembering BAND?
Me and all those friends who want to make variable power supply in less money are eagerly waiting for your video which you promised to teach us how to vary the current of power supply.
I can't wait to see more of this! What a cute little antenna! I wonder how many "channels" of usable frequencies this has, and what if two different units are on the same frequency? I will look into this more. Thanks for sharing. Have a great day!
best regards as it is works in commercial GSM frequency band and it don't have any interrupting communication link. it is one to one end UART communication, that means it is sending some coded signal for its receiving end moreover it depends on every country's regulations.
