Hamshield mini packet transmission size about hamshield HOT 3 CLOSED

The AFSK_SerialMessenger app was originally built to support APRS, which has a maximum packet size of 256 bytes. We'll be leaving the official library as is for this reason.

It should be possible to update the code to support larger packet sizes, but there will be a lot of bookkeeping variables to changes. In particular, there are a variety of counter variables (like currentByte) in packet.h that are defined as uint8s. Those would need to be changed to larger variable sizes. I haven't tested this, so you may run into some other issues as well.

The main limitation probably has less to do with the HamShield library than with hardware. I'm not sure you'll be able to hit 10k chars in a packet if you're running this on an Arduino. The Arduino Uno only has 2k of memory in the first place. If you used a Raspberry Pi, you shouldn't be hardware constrained. For details on that, see here: https://github.com/EnhancedRadioDevices/HamShieldPy (you'll still have to modify the library to get this to use higher packet sizes)

Also, just recently, we got the raspberry pi zero w integrated with our hamshield mini,'
Pulled the source codes and examples on python for raspberry pi including all requisite configuration but we noticed that you don't have an implementation of your AFSK_SerialMessenger in the python implementation as is in arduino C language implementation; the only examples available in your hamshieldpy library are below:

AppSerialController.py
ArduinoLikeExample.py
CTCSS.py
DTMF.py
FMBeacon.py
FoxHunt.py
HandyTalkie.py
Morse.py
SSTV.py

Is there an equivalent implementation of your AFSK_SerialMessenger in python for pi zero w?

If yes or no, please point us in the right direction.

Thanks you very much
