Problem with migration from basic nRF24L01 to long-range version.

Hello everyone!

Please, assist. I've built a remote control system prototype for an RC boat using basic, short-range nRF24L01 modules. Everything works perfectly and i decided to order another version with an amplifier and antenna to get a longer communication range. I've replaced the modules keeping wiring schema excat the same, but nothing works :frowning: Does somebody have a positive experience with long-range modules? Do i nee extra software setup for an exdended version? Maybe i am missing some hardware components or wiring? Please, assist and thanks a lot in advance!

The long-range model needs more current for the amplifier so you may need to use a larger power supply.

You don't need to change the sketch at all. As Pete says, maybe it's a power issue. I use a small regulator like this to power the nRF modules with 3.0v

Power the nRF with that separately, and connect the ground of nRF and arduino together.
Make sure you don't power up the nRF without an antenna attached, or it may suffer damage.
