Hi @eric, i’ve used BLEScanner app (android) in order to read the CCCD value, both from a BluzDK device and an HM-10 device as Peripheral. The results i obtained are shown in the following figures:
a) when connecting to BluzDK, and trying to read de CCCD value by pressing the signaled R button, no info is aparently read, and no additional info is shown.
b) when connecting to HM10, and following the same procedure in order to read the CCCD value, it appears to be successfully read and the “Notifications or indcations disabled” info is shown.
… so it reinforces the fact that maybe BluzDK doesn’t support the CCCD value to be read … could you please verify it following this procedure, or any other you consider, in order to conclude if it is possible or not, and make it possible? thanks
Edit: I’ve sucessfully written the CCCD value from a Red Bear Duo acting as Central to a HM10 device acting as Peripheral, so the problem seems to be on the BluzDK device.
