Hi,
We are using Quectel-MDM9206 BG96 module EVB. In our application we initiate data call (qapi_DSS_Init…).
- We are able to connect consistently with Airtel (network operator in India) - (airtel.isf)https://drive.google.com/open?id=1QP18pbAGZlhCzOBL0u1yYgVu58pnqGr6
- But connection with Vodafone (another operator here) is very rare (once in 10 attempts, all other times it returnsQAPI_DSS_EVT_NET_NO_NET_E). (Vodafone.isf)https://drive.google.com/open?id=1DbQonDeDup_Ur5DjzOdSalU7EjAP700f
- We have a team testing this application in USA (VZW) . We have a similar but different problem where post initiating the call through qapi_DSS_Start_Data_Call we never receive any information through the callback. The application waits indefinitely for connection success/failure event. (VerizonW.isf)
We have attached the 3 logs to this case. Please help us fix this issue
Thanks & regards,
Prathyusha
Hi,
Please try following AT commands:
i. AT+CPIN?
ii. AT+CSQ
iii. AT+CREG?
iv. AT+CGREG?
vi. Take QXDM logs
v. AT+QIACT=1 (should start data call and display already assigned IP address)
vi. Take QXDM logs
CSQ needs to be more than 10 , CGREG and CREG should have 0,1 .
Please also try to change data call settings to default
thanks
