Vodafone Global Roaming Profile Activation (Before First Time Registration of the Device)

This AT-commands activate the Vodafone global roaming profile. Usually used for the initial attach of the device to a cell.

//activate the Vodafone global roaming profile
> AT+UMNOPROF=197
OK
//reboot the device
> AT+CFUN=15
OK

Vodafone Germany Roaming Profile Activation (Before First Time Registration of the Device)

This AT-commands activate the Vodafone Germany profile. This should be used in Germany only. It results in a much faster initial attach. Usually only used for the initial attach of the device to a cell.

//Set the Vodafone profile
> AT+UMNOPROF=19
OK
 
//Module reboot for saving changed profile
> AT+CFUN=15
OK

Full functional test of modem (Attach, UDP Socket, TX, RX, Detach)

This AT-commands performs a full E2E data transmission to the cloud. Please make sure that the proxy IP address (213.136.81.171) is whitelisted at the operators APN (Access Point Name).

// Start network registration
> AT+CFUN=1
OK
> AT+CEREG=2
OK
 
// Wait till registered to network
> AT+CEREG?
+CEREG: 2,5,"AB7D","790066",9
OK
 
// Open UDP socket
> AT+USOCR=17
+USOCR: 0
OK
 
// Transmit "Test" to Exelonix UDP proxy
> AT+USOST=0,"213.136.85.114",9876,4,"Test"
+USOST: 0,4
OK
 
// Data indication (seems to be unreliable)
+UUSORF=0,3
 
// Receive response data "400"
> AT+USORF=0,3
+USORF: 0,"213.136.85.114",9876,3,"400"
OK
 
// Close socket

  • RED: Device is powered on
  • GREEN: device is registered in the network

/ GPIO2, red LED: global LED enable
> AT+UGPIOC=23,0,1
OK
 
// GPIO1, green LED: Power, Attached
> AT+UGPIOC=16,2
OK
 
// Reset the device to make setting effective
> AT+CFUN=15
OK
