Hi tamil_ram:
The parameters you configured have gone beyond the range given in the manual. I think our module does not support the parameters you defined by yourself.If the parameter Settings given in the manual work correctly in your module, then your module is currently working correctly, and your custom parameters may be implemented in a later version.

Hi Herbert,

Access barring bitmap is 10 digit value ( 0-9) ( 0000000000 - 1111111111 ) . as the network support access barring ( 10000001 01) corresponds to AC 0 , AC 7 & AC 9 . so if i understand your comment we can only set any one of the value . it can be either ( AC 0 , AC 7 or AC 9) .
Please correct me , if i am wrong in my understanding.

Also for special Access barring it starts with AC 11 - AC 15 .

questions :
1.) does quectel modem support AC from ( 0 - 9 ) .
2.) does quectel support special AC from ( 11-15) .

if it support above , can you please tell the exact command how to set them ?

Thanks & Regards,

Hi, tamil_ram:
It’s great to see you delving into “Access Baring,” I wonder where the knowledge you know comes from. I hope you can share with me.The content about “AT+CLCK” in our company’s current products is limited to the content in the screenshot above.
