I have a problem with the predictive maintenance setup as described in UM2639 and dm00659285..". I get as far as "Edge computing setup complete". Then it completely stops. Any ideas?

[PHarl.1]

The handshake sequence looked a bit odd too.

[STMdemo1] (08:07:40): {"state": {"reported": {"Device_Type": "STEVAL-IPD005V1", "Features": [], "Firmware": ""}}}

Update request with token "40d4c70c-ec71-4946-9f7b-b6ad2719d965" accepted

I have also tried a manual boot using /home/root/start_pmp.sh where it gets one step further with "Demo running..." then stops.

Any help appreciated. Phil

Hello Phil,

yes, you are right, the handshake sequence is missing the features and the firmware version; it should look, for example, like this:

[<device>] (<timestamp>): {"state": {"reported": {"Device_Type": "STEVAL-IPD005V1", "Features": ["Environmental", "Inertial_TDM", "Inertial_FDM"], "Firmware": "Firmware Ver.1"}}}

Have you tried to compare the output log to the log reported in Chapter 4.1 of the manual? Can you post it here, please?

Moreover, have you tried to flash again the firmware of the sensor devices and the master board?

Regards,

Davide

Hi Davide ,
I think you are right, I'll reflash the sensor and master boards. Current log is
