This document is a reference guide to all the AT commands defined for QuecLocator. l e t l c a e i t u n Q ide f n o C 1.1. Scope of the Document QuecLocator function is applicable to the following modules: UC20 UMTS/HSPA+ series UC15 UMTS/HSDPA series 1.2. General Process of QuecLocator Step 1: Configure and activate the PDP context. 1) 2) 3) Configure the PDP context parameters of, , and other parameters by AT+QICSGP (Please refer to Quectel_UC20_TCPIP_AT_Commands_Manual for details). If QoS settings need to be updated, configure them by the commands AT+CGQMIN, AT+CGEQMIN, AT+CGQREQ, and AT+CGEQREQ (Please refer to Quectel_UC20_AT_Commands_Manual for details). Activate the PDP context by AT+QIACT. Configure the PDP context ID for QuecLocator by AT+QLOCCFG="contextid", . Step 2: Get the location information by AT+QCELLLOC. Step 2 can be repeated. 1.3. Error Handling 1.3.1. Executing QuecLocator AT Command Fails If you execute QuecLocator AT command and receive response “ERROR” from UC20 module, please check if the SIM card is inserted and AT+CPIN? is in “+CPIN: Ready” status. QuecLocator_AT_Commands_Manual Confidential / Released 5 / 11 UMTS/HSPA Module Series QuecLocator AT Commands Manual 1.3.2. PDP Activation Fails If you failed to activate PDP context by AT+QIACT command, please check the following aspects: 1. 2. 3. 4. 5. Query whether the PS domain is attached by AT+CGATT? command or not. If not, please execute AT+CGATT=1 command to attach PS domain. Query the CGREG status by AT+CGREG? and make sure the PS domain has been registered. Query the PDP context parameters by AT+QICSGP command and make sure the APN of specified PDP context has been set. Make sure the specified PDP context ID is neither used by PPP nor activated by AT+CGACT command. According to 3GPP specification, it only supports three PDP contexts activated simultaneously, so you must make sure the number of activated PDP contexts is less than 3. l e t l c a e i t u n Q ide f n o C If the result of checking is OK, but you still fail to activate PDP context by executing AT+QIACT command, please reboot the UC20 module to resolve this issue. After booting the UC20 module, please check the terms mentioned above at least three times and each time at an interval of 10 minutes to avoid frequently rebooting UC20 module. 1.3.3. Error Response of AT+QCELLLOC If “+CME ERROR: is returned after operating AT+QCELLLOC, please re-execute AT+QCELLLOC. If it fails again, you should deactivate the PDP context by AT+QIDEACT command, and try again (Please refer to Chapter 1.3.2).
