I'm working in a POS(iPad) application where we are using Verifone E355 for payments. Now I have a requirement to trigger the barcode scanner of verifone e355 device(https://www.verifone.com/en/us/devices/mpos/e355) through software from iPad.

VMF(Verifone mobile framework) iOS sdk is being used to communicate calls with E355.

I have followed the framework docs and initialised the barcode scanner API. To activate the barcode scanner and scan the below code snippet is used.

I always get a return of -9 (which is an error code, description as per docs - Value returned when command was sent when device is connected but not connection not initialized) upon calling startScan and sendTriggerEvent: api's.

[self.barcodeScanner initDevice];
int startScanResult = [self.barcodeScanner startScan]
int setSoftTrigger = [self.barcodeScanner sendTriggerEvent:true];

The above code block is what I have tried till now. If anyone has experience working with e355 integration, please help out here.

you need to confirm to the delegate of VFIBarcode and once you scan you will get response from barcodeScanData delegate method.

  • I had set the delegate and had delegate methods implemented too. What I missed was adding bluetooth protocols in info.plist file. So the sdk couldn't establish a session with the E355. Thanks for your response. – jegadeesh Jun 17 '19 at 06:50
  • I haven't tried it. You can contact verifone support team for sdk related help, they seem to respond quickly. – jegadeesh Jun 17 '19 at 10:55
  • because I am making connection over wifi it works for iOS native app but I had created Cordova Plugin for VMF framework and integrated to Cordova app but delegate methods not being called from plugin any idea? followed these comments from https://stackoverflow.com/questions/32719016/callback-to-cordova-plugin-from-objective-c-delegate but no luck. – pratibha reshmi Jun 17 '19 at 10:57
  • Seems this is related to cordova bridge. If you know how to create a custom plugin on your own and still facing some issue please raise a question with sample code and explain whatever you have done. Else explore on creating a custom plugin for Cordova in depth, for which you can get a lot of references in internet. – jegadeesh Jun 18 '19 at 04:58
