Telemetry beep alarms

[grezlo]

Hello! Thanks for a great product!
I want tuning it on this way: add a beeper 5V, and to inform them about the battery and RSSI.

219 telemetry_data.volt1 = chanval.value;

What is the range of values for this parameter?

If I remember well it's vbat*10, ie 42 for 4.2V, but this has to be checked.

You wrote:
if (packet[0] == 0x85 && packet[14] == Bayang_checksum()) {
// uncompensated battery volts100
chanval.bytes.msb = packet[3] & 0x7;
chanval.bytes.lsb = packet[4] & 0xff;
telemetry_data.volt1 = chanval.value;
So vbat100 correct? Thank you!

And RSSI is 0-100 parameter correct?:
telemetry_data.rssi = Bayang_telemetry_count * 2;

I don't remember, just try and add some serial logging if required ;)

[grezlo]

Well I will write you about the results. Thank you!

Also, keep in mind telemetry range is very short as the H8 mini, B03 and other "Silverizable" quads do not have a PA.

[grezlo]

What about E011?

[goebish]

Same as B03, none of the supported model has a PA onboard.

[grezlo]

There is no possibility to add an amplifier? :) like PA LNA Wifi modules

[goebish]

No.

[grezlo]

Ok. Will short telemetry :/ 100 meters really?

[goebish]

Way less than 100m ... even indoor, telemetry stops working 1 or 2 rooms away. But that's not a big deal, you still have control ...

[grezlo]

For check the VBAT need flying closer to myself)

[goebish]

Yes, that's the only way ;)

[grezlo]

Thanks again. Will try.

rssi is about 200 normal operation, so not 0 -100
