It works great. There should be several ESP32 samples for BLE. Look for the SimpleBLEDevice under the examples for ESP32. It allows simple tx/rx to a phone/tablet etc. You might also checkout the nRF Connect app from Nordic for debugging.
Good luck

Mounting SD Cardposted in FAQS
Hello,
I recently received several (6 actually) M5Stack devices. After doing the capacitor mod, I've been able to download and test the supplied demos. Working with the FactoryTest sketch, I'm having problems mounting the SD Card. Here is my serial debug output:[W][sd_diskio.cpp:137] sdCommand(): no token received
[W][sd_diskio.cpp:137] sdCommand(): no token received
[W][sd_diskio.cpp:137] sdCommand(): no token received
[W][sd_diskio.cpp:471] ff_sd_initialize(): GO_IDLE_STATE failed
[E][sd_diskio.cpp:739] sdcard_mount(): f_mount failed 0x(3)
Card Mount FailedI've tried other SD Card sketches with no luck. I've tried formatting (Windows & SD Formatter App) three different 3 (64gb microSD) sd cards also no luck.
Any help would be appreciated!
