Quectel MC60 micro Second Delay

I want to know is there any way to make micro second delays?
I mean Ql_Sleep() in SDK accepts time to wait in milliseconds but i want to wait micro seconds. how can i do that?
Or is there any way that i can get tick count of microcontroller?
thanks in advance.


There is no tick counter or any timer for creating microsecond delay on OpenCPU.

I use the code as follows, and get some records for your reference.
