Some of the boards do support BLE in UIflow, specifically Core2, Fire, and Tough show Blynk BLE and Nordic BLE UART services under the Advanced menu.

There doesn't appear to be general support for custom BLE services and characteristics in UIflow itself at the moment, but the micropython modules may still be present in firmware, I haven't looked yet. If so, you could potentially run them from an Execute block, or someone could make a custom block for common BLE services.

Whether it's intentional or a coincidence, the boards that show BLE support in UIflow all happen to have psram, so it's possible they did that to avoid crashes that would be hard for inexperienced users to diagnose.

On the other hand, UIflow doesn't show any BLE services for Atom psram and M5Stack paper, even though they both have psram, but that could be an oversight.

While not quite the same, on the Core 2, Tough and Fire boards you can use Advanced > BLE UART in UIFlow (or the equivalent Micropython/ Arduino/ESP-IDF/Zephyr code) to wirelessly send logs to any Nordic BLE UART terminal, including web NUS consoles like https://wiki.makerdiary.com/web-device-cli/

Just visit that page on a BLE enabled desktop using Chrome or Firefox and pair your device once it has BLE UART running. Even works to send commands back to the M5stack if you set up receiving in your esp32 app.
