NRF24L01 differences

jaymark.ablero 15 Sept 2017, 00:08 last edited by

In terms of range of transmission does NRF24L01 with SMA antenna improve range than NRF24L01 without SMA antenna?

It depends if you want to use an antenna with some gain or not

Yes its for an Sony Product, because i tested around a bit. The IP is unique and the mac was also tested with DE:AD:BE:EF:FE:ED with no results

@mfalkvidd Thank you! It works. I was searching for "A0" not the GPIO number (newbie here) Thank you once again.
Finally, progress! (evidence based radio testing method) (and capacitors)

@TRS-80 There's an argument for putting two different value capacitors near the nRF24L01 (or whichever radio you're using). A 0.1uF bypass cap to help filter out noise, and a higher value cap as insurance against possible battery ESR and/or inductance from possible long battery leads/traces. For example: https://www.openhardware.io/view/480/Compact-nRF24L01-Pro-Mini-Bottom-Shield#tabs-design

@fets So far, I have only built the 5x5 board (but the others should be schematically identical). The only issue I have found so far is that I cannot get the ISP port to work. But I have checked and I have an identical setup on the 1.0 board and that worked, so I suspect the programmer is too weak to drive the net on this one. So it is not a board-issue per se, and might only be an issue on the 5x5 board as routing is the most complex on that one due to the size.

@Shivanand-Chanderbally I recently finished a node using the acs712 and found it to be very sensitive to nearby magnetic fields. It is best to have it as far away from these as you can.

Thanks for the tip!. It looks like a USB powered Arduino Nano cannot handle the long range radios power requirements. I powered the radio module independently and I can send commands succesfully again! The range has not improved, though, but that's another matter... Thanks !
