Nicla Sense ME ESLOV communications

Projects General Guidance

Hello, I'm trying to run an Edge Impulse model on the Nicla Sense ME, but with the 64 KB RAM limitation I'm running out of memory.

I have a Portenta H7 Lite (no radio connectivity) and was thinking I could use that as a host (via the ESLOV) to run the model since it has more RAM.

My question is: can I run the model on the Portenta, then send the inference back to the Nicla Sense ME so I can use the BLE capability? Or once the host/sensor relationship is set up, you can only read values from the Nicla Sense?

Thanks!

Can you use external memory such as FRAM (32K x 8) under $5.00 US. You could also interface static ram with a few serial to parallel and parallel to serial chips to almost an unlimited amount. These solutions will not be directly accessible to the processor but accessible by I2C or SPI depending on your choice/design. FRAM will remember without any power, it is ast NVM.
