Hi,

This is strange behaviour.
If you have any other SL8090, is the problem appearing in that also?
You can contact you FAE/ Distributor for the firmware packages.
please share the results with the new firmware.

Thanks

Hi Rex_alex
Thank you for your help.
More progress, I connect this module to USB and every AT-command above work well. I still waiting for new firmware from FAE.

As far as I can recall there is a mapping command. Might be that the UART is not mapped to AT command port but to the modem port instead.
Modem port returns OK for most AT commands I’ve noticed.
(My testing of modem port was done with the USB-endpoint rather than UART directly)

In addition, I don’t think you can use WIP commands at all on SL8090 currently.

Hi tobias
Thanks for your help, it work.
I use AT!MAPUART=1 to solved problem.
