I this current verison and would like to update it
(sysname='FiPy', nodename='FiPy', release='1.18.1.r2', version='v1.8.6-849-f652205 on 2018-10-17', machine='FiPy with ESP32', lorawan='1.0.2', sigfox='1.0.1') can't find the instructions on how to do that. If someone can provide links and insturcation that would be great. Thnx

To avoid migration problems from firmware 1.18.x to 1.20.x (with WiFi bugs, etc) :

so use the command "pycom-fwtool-cli" (see https://docs.pycom.io/advance/cli/) :

$ pycom-fwtool-cli -p /dev/ttyACM0 erase_all

Before installing the firmware v1.20.x.
