So far I have found no BT terminals for neither Windows nor Linux.
The testing of Rx/Tx must be done with Android Bluetooth terminal.

Hi.
Instead of the “regular” BLE library, you can use the NimBLE that uses the same methods but occupies much less space. https://github.com/h2zero/NimBLE-Arduino
I haven’t tried it myself , but heard very good feedback.

Regards,
Sara

My issue is that my app behaves great, a BLE keyboard mimic works great IN SECLUSION… the moment I combine the BLE Keyboard mimic together with my (facial recognition) app the linker complains I’m out of IRAM (just by 116 bytes!) and I can’t find away around this … an article covering reduction of IRAM WITH EXAMPLES would be really handy, perhaps others are having a similar issue?
