Quick question as I can’t find the answer to my question.
I’m going to get an rf24 module with an sma antenna to extend a project, so the outside temp can be taken and displayed on the same oled display, which already shows an indoor temp.
Do I need two rf modules with sma antennas, or can it be paired with a regular rf24 modules with an on board antenna and still get a decent range.
The modules with the PCB antenna will work fine with the modules with external antennas. However you may find that if the high-power module is too close to the other module they won't work.
JCA34F:
If the receiver never transmits, then only the transmitter needs a power boost.
Normally both of them transmit as the "receiver" usually sends an acknowledgement. This feature can be disabled, but then the "transmitter" has no means to know if a message was received or if it needs to be re-transmitted.
