Hardware Portenta Portenta H7
1

When you first plug in the Portenta H7 into a USB-C host, the device powers on and the Green and Blue LED start blinking at their own rate. I was wondering if this sketch was made available to the public and if so where? This hello world of embedded platforms seems like the logical starting point for most people getting this in their hands for the first time and my want to flash to a known good firmware in the event of a bug.

Is this source code on GitHub? Where is the code running? The M4 core or the M7 core? Or is Blue being blinked by M4 and the M7 is blinking the green LED?

Hi Dygear,

The Arduino PRO webpage has some great tutorials for the Portenta.

Hope the Arduino team will post some BLE tutorials for the Portenta soon. The Arduino IDE example BLE tutorials do not work with the Portenta at the moment

File->Examples->ArduinoBLE->Central

File->Examples->ArduinoBLE->Peripheral

... and the IDE Portenta Examples do not have BLE sketches at the moment

File->Examples->Examples for Arduino Portenta H7 (M7 Core)

Great question.
