How can I remove the data from mbientlab sensors? another way to say that how can I free the memory from old data?
There is a "clear entries" API call you can use.
Here is the CPP doc: https://mbientlab.com/documents/metawear/cpp/0/logging_8h.html#a70edf0c3932da841bc31311e3fb3cd11
Otherwise a firmware update would do the trick as well.
I use the MetaBase from my iPhone and I used update firmware but still there some data as well
by the way, I'm not familiar with CPP.
You can swipe left and delete old sessions.
Please see the tutorial videos here: www.mbientlab.com/gettingstarted (links are in the MetaBase details).
Thank you Laura,
As I understand, maybe these data are stored in the device (cellphone, laptop) if I don't use the collected data button. otherwise, it will be stored in the memory of the sensors. if so how can I clean the memory of the sensor?
It clears itself automatically when you download the data into the phone. You do not have to worry about data/memory management at the sensor level at all.
