M66 default firmware

Hello Rahul,

I think M66FAR01A12BT, that is what printed on module label.
Actually, I am developing custom application by using OpenCPU.
I am facing problem with Quec location things.
This “AT+QCELLLOC” and “AT+QLOCCFG” not working as per my expectation.
So, I thought to rollback to it’s factory program to test them.

I got M66_OpenCPU_GS3_SDK_V2.4_Eclipse.

According to Mr. Kyson here M66_opencpu_ble
He was suggesting to use SDK V2.0.

In next i am going to use bluetooth functionality.
Overall I am started confuse about my environment setup.
Please guide.

Regards,
Umesh
