I think the Jammer deserves a green icon, since it actually does it job pretty well.
Then there is a Jitter parameter. It allows to introduce a jitter from 1/60th of a second up to 60/60th of a second (a full one). It will delay / move forward either the TX or the cooldown period for a maximum of a half of the time you choose as jitter.
Meaning: If I choose 60/60th, a full second of jitter, it will produce a random number from 1 to 60.
Then it will calculate jitter = 30 - randomnumber
THen it will "add" that (positive or negative) time to the time counter for the next jitter change of state.
Several old bugs squashed.
On the APRS side, most notably, SSID numbers where shifted left twice, instead of once, and bits 5,6 where not properly set.
On AX.25 side, the bit stuffing part of the encoder was not placing the zero bit on the right place.
Finally, I changed APRS icon from ORANGE to GREEN, since even this may be a simple app, now it's doing its work as intended.
Values where left bit-shifted upon being entered by the user, so resulting SSID being transmitted was a different number. This shifting was happening both on Source and Destination SSID values.
* No device freeze when you try to close app while it's transmitting
* Bypassed 100 .wav files limit by implementing paging functionality
* Removed useless progressbar and implemented page info line instead
Moved the MIC TX RX into the main menu.
Changed scanner color from yellow to green, since it is kind of rounded up into an acceptable functionality.
Also, did a bit of cleanup on the code spacing inside the menues.
Also added the fields "DateTime" which just shows the raw timestamp that portapack assigned the last packet received, in the format: YYYYMMDDHHMMSS ... And "Frame" which shows the packet # (or frame) for correlating with other software / verify that there are new packets being received.
Also moved a string function for returning rounded-up decimals, originally inside the whipcalc tool app, into the string_format functions library, because I used that function on TEMP and HUMIDITY values inisde the radiosonde app.
Finally, the whole UI has its widgets moved a bit, giving space for these new parameters.
Thanks @euquiq for a more common solution to the bug.
Added RX gain control.
Now we have full gain controls!
Merged PTT and Voice activation into one option selector.(allowing RIGHT BUTTON to work with PTT off)
This patch addresses the issue detected in: https://github.com/eried/portapack-mayhem/issues/159
This patch will revert the behavior of the function to_string_short_freq
into using spaces on the left of the integer part of the frequency (as it did originally).
When upgrading the scanner app, I did change the behavior of this function eliminating those spaces, so I could gain some characters-worth of space inside the scanner, but I failed to detect that it introduced some lack of padding on the rx->audio app.
Now, it is back as before, and I also did update the scanner so it can cope with the "extra spaces" this function now adds (again).
A bug that enabling audio RX resets the TX gain (perhaps because that changing to receiving mode modifies some registers) inspired me to add this gain control.
Commented out some steps which don't require for the VU meter to work again.
Moved some widgets for gain control.
Added CRC calculation for Vaisala radiosondes.
Added a Checkbox on APP for turning ON / OFF CRC. When CRC on, malformed packets are ignored.
Connected existing CRC function for METEOMAN sondes, using the same "CRC" checkbox logic.
