Obtain the read characteristics values from nRF52840 DK (peripheral) to Android studio TextView

[javalearner]

Hi,

I am trying to perform the read characteristic values from the nRF52840 DK to Android studio (Java) to a TextView. I have looked at the Android Blinky example but in the code, the ViewModel does not seem to how to retrieve the string values to the TextView (it is only LED and button on/off). I am wondering can someone explain how to obtain the read characteristics values from nRF52840 DK (peripheral) to Android studio TextView?

Thanks!

Hello,

We don't provide support for Android studio Textview. But after discovering the services you can make use of the function sd_ble_gattc_read() to read the characteristics. You can find the exact message sequence chart for the function here.
