sendTxPowerLevel and sendSignalStrength

manutremo

Hi, I'm interested on using the functions in the post title. I'm running Mysensors 2.2.0., and I have

#define MY_SIGNAL_REPORT_ENABLED

in my sketch.

If I add something like

sendSignalStrength (6);

or

sendTxPowerLevel (6);

to my sketch, the Arduino compiler complains about undefined references.

What do I need to do to get them working?

Thanks.

With pleasure, too, I want comments from the founding fathers. How to use? Linker error.

Hi,

when you enable MY_SIGNAL_REPORT_ENABLED, it should automatically send signal quality to the controller. Ideally controller could handle this message type. It is an internal message type I_
I think these two functions doesn't work because they aren't implemented yet, maybe simply an oversight or an artefact :)

To directly get the signal value, you can use transportGetSignalReport() .

If report is not available for a particular mcu, or a radio module (because of not provided by the hardware itself or not implemented yet), then it should return INVALID_RSSI, INVALID_SNR, INVALID_PERCENT, or INVALID_LEVEL

@scalz said in sendTxPowerLevel and sendSignalStrength:

they aren't implemented yet

this is the most important..

@berkseo
yes, until now it has been implemented for rfm radios only, as nrf24 doesn't provide true rssi value. As usual, features appears along interests.
So if you want it for nrf5, maybe post/PR your snippet on github ;)
On my side no time for testing this, my mysensors HA isn't 2.4ghz based as I need longer range, and keep 2.4ghz bandwidth in case for others protocol (wifi, ble, zigbee) for limiting issues.
