Downgrading firmware (advanced users)
We have recently updated our upgrade tool to simplify the procedure of performing a firmware downgrade. It can now be performed using either the GUI version of the tool, or the CLI version. The most upto date instructionsfor how to perform this can be found here: https://docs.pycom.io/chapter/advance/downgrade.html
We have made previous firmware versions available to download here:
Note: Prior to version
1.16.0.b1the firmware for modules with LoRa functionality was frequency specific. From
1.16.0.b1and onward, the firmware is region agnostic and this can either be set programmatically or via the config block (see here)
Please go to new topic this is really unreleated one
