I want to connect my „Freematics one white BLE“ with my iPhone. But the phone can’t find the „One“. What can I do? Which App can I use for monitoring the data? Sorry for my bad English
to make bluetooth work you have to implement a FW on the FreematicsONE that use it.
From the given example no one implement bluetooth.
However you can download the esp32 bluetooth library wich contain some example to make a bluetooth advertising scan or connection and make it visible and connectable from you phone.
