    Hi,

    please check the value of 'console_enabled' configuration variable. It must be '2' to enable uPython and '3' to boot from the python script specified in the 'python_script' configuration variable.

    You can find these and more details in the application note 'AN4964: MicroPython scripting language over SPWF04S'

    As I said, I followed the istructions in the application note. Therefore, I set 'console_enabled' to '2' but the answer is like this:

    And I checked the value of 'console_enabled':

    I found a solution. After change 'console_enabled' to 2, I need to save the configuration variable to no volatile storage (AT&W).

    Restart the module and now shell started.

    Thanks for the support.
