    Hi Julien,

    Not aware of this issue.

    Can you walk me through a step by step.

    I will look at the logger log soon, but understanding what you are doing will also help.

    Hello :)


    here is what we do :
    We boot the chip with R7.2 firmware
    We role-up in station mode
    then we connect to a AP. 
    First connection succeed most of the time, but when i disconnect and want to reconnect to the same network, 
    i receive an error 0x3 from the event callback handler. 

    Some time i can do several connection / disconnection cycle without errors, some time it fail right after second attempt. 

    Maby could be make a little call so you can have a look at what i do and see if their is any big mistake in how we interface the chip ?

    Best

    Hi,

    I cannot see anything that is clearly causing the issue on the logs. Let me try and recreate this on out end and I will follow back with next steps.

    Hello, 

    ok. Can you see otherwise something in the log indicating proper connections ?

    Hi Julien,

    Three quick things you can try based on what I am seeing,

    1. can you try to role down then role up after disconnect and see if this improves behavior?
    2. Can you include a delay in between connect and disconnect?
    3. Can you include a delay in between disconnect and connect?

    I am not seeing a clear reason on the logs, I only see that at some point the device is struggling to execute commands because it thinks the wrong role type was set.
