Hi guys.
i'm working with 2.4ghz wireless module. I can send receive data just fine. Now i want to, estimate the signal strength for the receiver. anyone has any idea how to get or calculate signal strength using this module?
Thanks!
pin config
As far as I can see from the datasheet plus a little Googling you need to read Register 9, the RPD register.
...R
That is an nRF24 part. Are you using the RadioHead library with it?
I doesn't look that these guys give you a usable RSSI.
The hardware has:
In RX mode a Received Power Detector (RPD) signal is available. The RPD is a signal that is set high
when a RF signal higher than -64 dBm is detected inside the receiving frequency channel.
If you felt like hacking RadioHead to read out Received Power Detector (RPD), located in register 09, bit 0 you would at least know if the received signal is < or > -64dBm.
Thanks!
i was using RF24.
I just tried NRF24 (i tried to execute server-client ping example). For some reason it doesn't work. debugging shows it get suck in the "nrf24.waitPacketSet()"
anyway, even if i do manage to read RPD register 1 bit value won't be good enough for me. is there any other wireless module that provide higher resolution receiver signal strength?
