The AT command can be used in three ways. Performing AT+CPBS? will return the current storage location of the phone book. Such as +CPBS:<storage>[,<used>,<total>].The parameter <total> indicated how many phone numbers can be stored on the phone. The parameter <used> indicates how many phone numbers have been stored. Performing AT+CPBS=? will return all the storage type which the phone supports. Such as +CPBS：(list of supported <storage>s). We can use AT+CPBS=<storage> to set storage location. There are six types storage location. It’s follow as: “LD” --store the recently call number which have dialed (SIM). “MC” --store the recently call number which haven’t answered. “RC” --store the recently call number which have been answered. “ON” -- store the phone number of itself. “ME” --NVRAM storage “SM” --SIM storage 4.3.2 Read Phonebook entries When you want to read phonebook entries, you can use AT command AT+CPBR. Performing AT+CPBR=? will list of supported index, phone number length and text length. Performing AT+CPBR=<index1>[,<index2>] will return the content of the phonebook entry of index1. If we use
Page 29 of 31 index1 and index2 at the same time ,it will return all the entries between index1 and index2. Such as [+CPBR:<index1>,<number>,<type><text>[[...]<CR><LF>+CPBR:<index2>,<number>,<type><text>]] The parameter <type> include 129 and 145.145 indicate which is a international phone number. 129 indicate which is a unknown type number. The parameter <text> is the tag of the number. 4.3.3 Write phonebook entry When you want to write a phonebook entry on the phone, you can use AT commande AT+CPBW. Performing AT+CPBW=? will return list of supported index, max length of phone number, list of supported phone number types and max length of text. We can use the command “AT+CPBW=[<index>][,<number>[,<type>[,<text>]]]” to write number on the phone. If the parameter <number> is NULL, the command will delete the phone number on the phone of index. 4.3.4 Find phonebook entries We can use AT command AT+CPBF when we want to find the entry according to the text. Performing AT+CPBF=? will return the max length of phone number and the max length of text. Such as +CPBF:[<nlength>],[<tlength>]. When we want to find a entry, we can give the text of the phone number ,and according to the text, we use AT+CPBF=<findtext> to find the number we want. 4.4 AUDIO Audio functions are only available in the U6300_001 module. 4.4.1 AUDIO PCM data path selection We can use one of two option to select audio PCM data path. 1) audio path in the U6300. 2) the external PCM interface. The audio PCM data could be routed to external PCM interface and be input from external PCM interface. In this case, the audio path in the U6300 will be switch off. If user wants to use the external PCM audio path, then a CODEC IC must be used, and be connected to the external PCM interface of the U6300. The AT command AT+PCMAUDIO can be used to select which audio path we want to use: AT+PCMAUDIO=0, will select the audio path in the U6300; AT+PCMAUDIO=1, will select the external PCM path. AT+PCMAUDIO？will check the current audio path in use. All the values will not be saved after power off U6300,the default value is 0 while power on the U6300 , namely the default audio path is the audio path that in the U6300.

The Max length of dialing digits is 20; The prefix ”+” is not counted to the length of dialing digits. 4.4.3 Answer a incoming call ATA using the command can answer a incoming call. ATA responds coming call by RING. It will display the calling phone number if CLIP (Calling Line Identity Indication Presentation) function is set. ATA will return NO CARRIER for responding hang up after connection. 4.4.4 Disconnect call AT+CHUP using the command can disconnect a connection.
