I am using quecopen for M66. I can receive SMS by Android phones but can’t receive from iPhones.

Hi
Please check that the parameters passed into the function are normal. There should be no difference between Android and iPhone text messages

Hi,

I can receive SMS from Android successfully. But the IOS problem persists.
Is there any way to debug for your help?

Still no response from Quectel.
When I invastigate the problem I have encountered a problem.
If a message received by iPhone I see undefined header value on UDP format. The value is 0x24. If parser see this value within PDU, it return “Fail to read text SMS”.

My SDK version 2.4 and uses M66FAR02A09BT version. By the way if I use M66FAR02A09BT version with AT command. There is no problem. But problem persist with OpenCPU.
I also tried adding RIL lib but can’t read SMS.

Is there newer version of SDK?
