I am working with the SL Series Development Kit with an SL8080 socket board and when I try to open a port (either Serial or USB) in the Developer Studio I get: Open and load local port COM1 =\> ERROR: Time out: 20000ms Open and load physical port COM1 =\> ERROR: Time out: 20000ms Open port COM1 =\> DONE: Port opened Open port COM1 =\> DONE: Port opened Load informations from target =\> ERROR: Time out: 20000ms Waiting for module detection =\> ERROR: Time out: 20000ms I can communicate via Serial COM with TeraTerm (just sending AT commands), however, I cannot communicate at all via USB. I have all the accompanying drivers installed (they show up in the Device Manager), and I am working with the latest DS (2.3.1). Is there anything settings in the SL8080 module that I need change or set? What am I missing?! Thanks all. ---

I found the module I am working with was configured to enable AT commands on UART. I issued an AT!MAPUART=0 and AT!RESET to remap back to USB. And when I try to connect DS with USB I get the error message: Open and load local port COM28 =\> ERROR: An error ocurred during HAPC AT test Open and load physical port COM28 =\> ERROR: An error ocurred during HAPC AT test Open port COM28 =\> DONE: Success Wait for USB port to reconnect =\> DONE: Success Open port COM28 =\> DONE: Port opened Pause : 1000 milliseconds =\> NO NEED TO DO IT: Success Load informations from target =\> ERROR: An error ocurred during HAPC AT test Waiting for module detection =\> DONE: Target detected sn:null baudrate:null Switch to Development mode and check =\> ERROR: An error ocurred during HAPC AT test Switch to Development mode =\> DONE: Success Pause : 300 milliseconds =\> DONE: Success Check dev mode unlocked =\> ERROR: An error ocurred during HAPC AT test Switch to Development mode and check =\> ERROR: An error ocurred during HAPC AT test Switch to Development mode =\> DONE: Success Pause : 300 milliseconds =\> DONE: Success Check dev mode unlocked =\> ERROR: An error ocurred during HAPC AT test Switch to Development mode and check =\> ERROR: An error ocurred during HAPC AT test Switch to Development mode =\> DONE: Success Pause : 300 milliseconds =\> DONE: Success Check dev mode unlocked =\> ERROR: An error ocurred during HAPC AT test AND console output: AT+WMSN ERROR AT+CFUN=1 OK AT+WMSN ERROR atat OK atat OK atat OK ---

Is your module a T one? (SL8080T?) Because if it’s not the case, it is not able to run the Open AT Application Framework, and is not compatible with Developer Studio. ---

Dear bvalletta, [Have a look here](https://forum.sierrawireless.com/t/sl8082-use-openat/5622/5) to double check that your module is a T variant fo the SL8080. ---

Hi, I cant connect to the AT Command port, as I am using Window 11 and the drivers they have on their site are for window 7 and 8.1. Can anyone please help me with the updated driver so that I can connect to my module. ---

This product has been end of life. have you tried to install windows XP or Windows 7 on virtual machine and see if it can comunicate with the module? ---
