Hello,
In our Edge Actions, it’s straight-forward to use Datahub.read() to access the value of say, the light value on a mangOH Red:
var light_val = Datahub.read("/light/value", 0);
However, for a resource such as /util/cellular/signal/value – this value has nested information such as “bars”, “rx_level”, and “lte” (lte in itself has another layer of info). If I wanted to get the rx_level value using the following:
var rx_level = Datahub.read("/util/cellular/signal/value/rx_level", 0);
We get an error Edge side to the effect of:
Datahub.read: Failed to read from /app/util/cellular/rx_level
Our workaround right now is to use Datahub.read on “/util/cellular/signal/value” which we inefficiently have to send a larger payload over to our Cloud Action. From the Cloud Action, we get the rx_level using:
var rx_level = event.elems.cellular.value.rx_level;
We’re pretty sure this is something simple in basic JavaScript that we’ve missed. Highly appreciated if anyone can point out how we can get the rx_level or similar nested resource values Edge side.
Thanks!
Jason
