A possible alternative is MicroPython

, but it needs more than 250 (rather 350) KiB of Flash . What about uLisp

? It is also small (32 KiB) and self-contained, but it needs garbage collection, that takes about 2 ms @ 40 MHz (real-time programming and garbage collection is not a dream team).

BLE and other Middlewares

STM32WB Forth without BLE, USB, Filesystems, RTOS etc. is not complete, to build this by myself from the scratch overwhelms me. I would like to go the reverse way and use the STM tools like CubeIDE, HAL, CubeMX and integrate the Mecrips Forth into it. Forth as an interactive extension for the STM ecosystem. Mecrisp Forth running as a CMSIS-RTOS thread.

USB-CDC for serial communication
USB-MSC to make it possible to read and write blocks or include source files. INCLUDE vs BLOCK? Forth source files
Command line editing like Gforth
Calling HAL and other C functions
Calling forth words form C (prefix forth_ ?)
Event driven programming like LAIRD's smartBASIC, WAITEVENT ONEVENT.
BLE GATT (Characteristics, Services, Profiles)
