Can anyone tell me what error code 0x00003401 means (returned by sd_ble_gatts_hvx)?
Here's the documentation on that function
that lists all the errors it can return, and those link to the error codes which link to the base and offsets.
Hint . it's near the bottom of the list.
In addition to the documentation there are a lot of Q&As on this error code here on devzone.
