Trying to make the Pytrack to work wth the FiPy but keep getting the following error -

The Pytrack works fine with a LoPy except for some memory issues due to the new library hence I decided to switch to FiPy

[jmarcelino]

Can you try a different/better USB cable please? The FiPy has a higher initial current draw than the LoPy and some bad quality cables can't deliver the proper voltage

[tanmoydutta]

@jmarcelino thanks for your quick reply. Already tried two different cables. One specially made for chargers. Hence not sure if this is really the case. How else can I find out what is wrong ?

[jmarcelino]

Thank you, as a first step please try updating the firmware, the release you have is very old

Updated the firmware, still the same problem -

import os
os.uname()
(sysname='FiPy', nodename='FiPy', release='1.17.3.b1', version='v1.8.6-849-83e2f7f on 2018-03-19', machine='FiPy with ESP32', lorawan='1.0.2', sigfox='1.0.1')

Just to be sure I also updates the firmware on Pytrack board as well -

Conclusion - keep all files in the lib folder without a subfolder.
