Loading a different firmware via the fake mass storage may make sense first. Recent OpenOCD will work using the stm32wlx.cfg as target, however with the stock firmware in there that cannot connect unless the adapter actually asserts hardware reset during connection, which that file is not setup to. The demos will build with ARM gcc if you craft a Makefile and grab the startup code and linker script out of a project’s cube directory.

If using the demo software TTN users in some regions may need to change the default channel mask in Middlewares/Third_Party/LoRaWAN/Mac/Region and potentially define “HYBRID_ENABLED” to join only on preconfigured channels and not blindly stumble across the band only accidentally happening on the channel bank TTN gateways use in the manner of the “work with any network” aspect of the spec. STMicroelectronics NUCLEO-WL55JC1 Development Boards & Kits - ARM STM32 Nucleo-64 dev board, SMPS, supports Arduino, ST Zio & morpho US/Euro Freq. The job of those RF components is in part to filter out radiation on harmonics of the intended operating frequency, and they accomplish that quite well! The software can’t tell the difference, but the attenuation in using the wrong board for the operating frequency is impressive - detecting only the occasional packet at the edge of reception when right next to the gateway.
Beware that the -JC2 board has 433 MHz RF networks! Almost all TTN users will want the -JC1 board with 868/915 MHz RF components. NUCLEO-WL55JC1 Mfr.
