signal report functionality 2.2.0 to 2.3.2 changes?

[Nigel31]

Hi.
I have been using a child to report signal strength. All working on various nodes at 2.2.0
Gateway is now at 2.3.2
Nodes that thabe been upgraded to 2.3.2 now only ever report zero for the
send(msgRxRSSI.set(transportGetSignalReport(SR_RX_RSSI)));
I have set the define MY_SIGNAL_REPORT_ENABLED
Having found the requirement in the forum (didn't need to set in 2.2.0)
What else?

To reiterate builds of the same code in 2.2.0 work. Builds of 2.3.2 don't.

Suggestions please.

Regards Nigel
