rfeObj.SendCommand_SweepDataPoints(value) documentation says it accepts values from 16 to 4096 in multiples of 16.
I cannot get that full range to function. For the test below I tried values from 16 to 4096 in steps of 16 and read the resulting setpoint out as "rfeObj.FreqSpectrumSteps+1".
- Values from 16 to 112 all produce a setpoint of 112, which is reasonable
- Values from 112 to 2048 and the value 3136 works as expected.
- Values from 2064 to 3072 produce a setpoint of 3120
- Values from 3088 to 4096 produce a setpoint of 3136
refObj.SendCommand_SweepDataPointsEx(value) also produces odd behaviour.
The documentation says "a value in the range of 112-65536, note a value multiple of 2" though I can't figure out what "note a value multiple of 2" means in this context.
In the test below I tried values from 0 to 1024 in steps of 1 and read the resulting setpoint out as "rfeObj.FreqSpectrumSteps+1".
Values that work as expected:
- Values less than 112 produce a setting of 112
- Values from 112 through 127 work
- The value 195 works
- Values from 256 to 383 work
- The value 451 works
- Values from 512 to 639 work
- The value 707 works
- Values from 768 to 895 work
- The values 1024 works
Problem values:
- Values from 128 to 191 produce a setpoint of 194
- Values from 192 to 255 produce a setpoint of 195
- Values from 384 to 447 produce a setpoint of 450
- Values from 448 to 511 produce a setpoint of 451
- Values from 640 to 703 produce a setpoint of 706
- Values from 704 to 767 produce a setpoint of 707
- Values from 896 to 959 produce a setpoint of 962
- Values from 960 to 1023 produce a setpoint of 963
I didn't run an exhaustive test beyond 1024. It sometimes looks like this is a problem with bit 6 (0x0040) but it doesn't seem consistent. It carries on with problems at higher numbers but testing gets inconvenient because the lag time on ProcessReceivedString gets big. I did a few checks though: for instance the value 65407 produces the setpoint 50110, but the value 50110 produces the setpoint 50051 and the value 65280 produces the setpoint 50111.
I am using the IoT Module as follows:
