Pysense MPL3115A2 hangs rather quickly and consistently. #46
Description
This Pysense MPL3115A2 bug has been confirmed independently by two forum users, myself included.
Within a minute or two (it varies) below script hangs without any error message.
Serial communication also breaks down and a power cycle is required to regain communication with the LoPy Pysense combo.
