GSM Module CME Error code 15


GSM Module CME Error code 15



I am attempting to build a GSM/MCU project using a ADH8066 GSM module.



I have managed to setup a reliable serial comm with the unit, but now I am struggling with the sim card integration.



I am trying to make sense of the response: "+CME ERROR: 15" when attempting a "AT+CPIN?" command.



When the sim card is not present I receive +CME ERROR: 10 which is expected (SIM not inserted), but when sim is inserted and module is rebooted I get this 15 error. Can anybody advise me on what this means?



The Sim cards I have tried are South African sims registered on the Vodacom and Mtn networks here in SA.

+CME ERROR:15 tends to be because the modem can't work with the SIM card. This is usually the case with UMTS only network SIM cards.



ADH8066 GSM module is the evaluation board. But what is the modem you have integrated? Would be useful to know as then you can verify if its a simple GSM modem (which is what I am assuming).



As a side note the +CME ERROR: 10 error is based on whether the SIM card "door" is closed or not. It does not tell you whether all is good with the SIM card or not. Hence the differing error codes.



Here are meaning of ALL error codes :

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false. I added itms-apps to my plist: LSApplicationQueriesSchemes and put this in my app delegate: func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return true } func moreTapped() { let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877") if #available(iOS 10.0, *) { UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in }) } else { UIApplication.shared.openURL(url! as URL) } } Are you testing on a real device? – rmaddy Jun 21 at 23:57 I try on a device, get "Cannot Connect to App Store".

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
