Bug when trying to write to characteristic cb module

[E-AS-Pugh]

I am using the latest version of the app on an iPhone 17 running the latest software update.

The issue I'm encountering is that when attempting to write to a BLE peripheral (which I have already connected to and done all appropriate steps), I get an error related to the C code from the module. There is no other way to write data. I am using a byte string as instructed by the docs. Unfortunately neither of the examples in the docs use the write_characteristic_value method, so I have nothing to go off. The error message is below.

manager.selected_peripheral.write_characteristic_value(
SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

Any help would be appreciated, plus let me know whether it is worth contacting the app developer, whether they respond and are still working on the app.

Thanks!

Edit: found the relevant issue. #699 on the other repo.

It is currently fixed in beta as of 10 months ago. Not sure when Pythonista 3.5 will be out but until then I'm hoping to get beta access!
