I am using M66 GSM module and stm32f030xx controller for my project.
I want to know how do i know who is calling on my module?
I want to adda provision that my microcontroller store some phone numbers and what i want to do with that when incoming call is there i will compare the incoming number with stored number and accept the call accordingly.
can anyone tell me the flow of at commands and how to get that number store in a buffer?
I thought you might need the phonebook function,I think you can do like this:
- Excute AT+CPBS=“ME” to store the phonebook on the module or AT+CPBS=“SM” to store the phonebook on the SIM card;
- Execute command like the one in the following example to write a phone number:
You can use AT+CPBR=10 to read current phonebook entries.
- If you set it to ME,execute AT+CPBS=“ME” again after the module is restarted.
If you set it to SM,after rebooting the module, there is no need to excute AT+CPBS=“SM” . The default is SM, so you can read the phonebook directly.
If you want to see the number of incoming calls, you can also set AT + CLIP =1.
Thanks for reply.
Do i need to send AT+CLIP after every ring or it will get automatically called?
what is meaning of “QUECTEL” at the end?
How do I dial a number from phone book entry?
if i want to dial number stored at location 2nd?
1.AT+CLIP only needs to be set once and if you want this command to remain in effect after the module is restarted, you can set AT+CLIP and then excute AT&W to save it.
2.For AT+CPBW, you can refer to the instructions below:
For example,“QUECTEL” represents a mark for this phone number.
3.If you want to make a phone call, you still have to use “ATDxxxxxx” command.
How do i wake up the module from external MCU using GPIO?
Is it still about the M66 module?
Could you tell me the software version of the module?(Please excute ATI to check)
Yes the module is M66.
And version is
Thanks for the help.
I’ll implement these things.
When sms received on module does that produce signal on RI Pin?
I got the answer.
RI also get signal on SMS reception.
Ok.Wish you all the best!
how many phone number can be saved on m66’phonebook ? I read at command manual on page 131
“SIM phonebook record can stores up to 250pcs and ME phonebook record can store up to 100 pcs”
100pcs seems small number. I think m66 should do better.
The maximum phone numbers that can be stored is as stated in the document.
Thank you Winnie have a nice day
