GnsGroupReader.java:595: RSSI values > 0x0F observed. #37

Closed JacekRuzyczka closed 3 years ago

JacekRuzyczka commented 4 years ago

I've found out that as a response to opcode 0x6C (OPCODE_RSSI), 0x1A and 0x1F may be returned, so that 0x0F is not the upper limit you assumed.

Tested with a GNS FM9 dongle.

Thanks, good catch! That explains why the signal strength with the GNS FM9 looked so much better than with the other receivers… If you ever get a return value above 0x1f, please let me know!

JacekRuzyczka commented 3 years ago

The highest RSSI value I've been able to observe so far has been 0x2C.

mvglasow commented 3 years ago

That means the upper limit is probably at least 0x3F, I’ve created #43 to implement that
