I am sending AT commands to an android/ios device from windows over a bluetooth(hfp) connection and when I checked some AT commands like ATD,AT+CLCC,ATA,AT+CHUP give same results on all devices but AT+CNUM gives different results on different devices, so is it because of a different android versions or bluetooth versions.
I wanted to know on which sim i am getting a call if i have a dual sim device over a bluetooth connection with AT commands.
Right now on Oppo F11 pro (Android 11,Bluetooth v:4.2) AT+CNUM gives the sim number on which i am receiving a call but on other devices like pixel 6a,Iphone 12 pro, One Plus 10t it gives the default sim information not the one i am using for call.
