Is use of NETWORKID possible with LoRa RFM95

[jhoward88]

I see that the RFM69 library has the Initialize method that allows a nodeID and networkID parameter, while the RH_RF95 library has no such feature.   

Is there a way to use a networkID with the RH_RF95 library or any other way to limit received transmissions to a specific group or network?

I'm just starting to dig into RH_RF95.h and .cpp, but I thought if someone else has already solved this then I'm happy to not re-invent the wheel.

Did you get the LowPowerLab version or the Radiohead version ?

I'm not a 100% sure but I think this is handled it the LowPowerLab version Checkout this link:

There is no specific NetworkID. Instead, the radioHead Lib supply 2 others "meta" lib which are RHReliableDatagram or RHDatagram. They allows you to specify NodeID & GatewayID

Thanks!  I should be able to use those libs. 

Another question I have:  If you use an address, i.e., network ID and/or node ID,  will the receivers that are also set to that ID be woken up from from radio.sleep when a message targeting them is available?  Or does the device have to not be in radio.sleep and lowPower sleep modes?

Also, will they be woken up from radio.sleep if a message not targeted for them comes through the airwaves on the same frequency?

radio.sleep != radio.recv

From the doc :

Sets the radio into low-power sleep mode. If successful, the transport will stay in sleep mode until woken by changing mode it idle, transmit or receive (eg by calling send(), recv(), available() etc) Caution: there is a time penalty as the radio takes a finite time to wake from sleep mode.
