Does Quectel UC15 support AT+QSTK?

Hi
I want to buy Quectel U15 from online shop but need to be sure that it supports STK command.
Does Quectel U15 support command AT+QSTK?

Thanks

Hi bolons´╝î

I have looked up relevant materials, but there is no support for this order. Maybe you can confirm with sales or local FAE

Thanks
