SIM300D AT Command Set Confidential SIMCOM Set command AT+ILRR= Reference V.25ter Response This parameter setting determines whether or not an intermediate result code of local rate is reported at connection establishment. The rate is applied after the final result code of the connection is transmitted to TE. OK Parameter 0 Disables reporting of local port rate Note 1 Enables reporting of local port rate � If the is set to 1, the following intermediate result will comes out on connection to indicates the port rate settings +ILRR: port rate setting on call connection in Baud per second 0(AutoBauding ,see chapter 2.2.45.1 ) 300 1200 2400 4800 9600 19200 28800 38400 57600 115200 2.2.45 AT+IPR Set TE-TA fixed local rate AT+IPR Set TE-TA fixed local rate Test command AT+IPR=? Read command AT+IPR? Set command AT+IPR= Response +IPR: (list of supported auto detectable s),(list of supported fixed-onlys) OK Parameter See set command. Response +IPR: OK Parameter See set command. Response This parameter setting determines the data rate of the TA on the serial interface. The rate of command takes effect following the issuance of any result code associated with the current command line. OK SIM300D_AT_V1.00 Page 32 of 180
SIM300D AT Command Set Confidential SIMCOM Reference V.25ter Parameter Baud-rate per second Note 0(AutoBauding ,see chapter 2.2.45.1 ) 300 1200 2400 4800 9600 19200 28800 38400 57600 115200 Factory setting is AT+IPR=0(autobauding).It can be restored with AT&F and AT&Z when you modified the bit rate’s value.. 2.2.45.1 AutoBauding Synchronization between DTE and DCE ensure that DTE and DCE are correctly synchronized and the bit rate used by the DTE is detected by the DCE (= ME). To allow the bit rate to be synchronized simply issue an "AT" or "at" string. This is necessary when you start up the module while autobauding is enabled. It is recommended to wait 3 to 5 seconds before sending the first AT character. Otherwise undefined characters might be returned. If you want to use autobauding and autoanswer at the same time, you can easily enable the DTE-DCE synchronization, when you activate autobauding first and then configure the autoanswer mode. Restrictions on autobauding operation � The serial interface has to be operated at 8 data bits, no parity and 1 stop bit (factory setting). � Only the strings .AT. or .at. can be detected (neither .aT. nor .At.). � Unsolicited Result Codes that may be issued before the ME detects the new bit rate (by receiving the first AT command string) will be sent at the previously detected bit rate. � The Unsolicited Result Codes “RDY” and so on are not indicated when you start up the ME while autobauding is enabled. � It is not recommended to switch to autobauding from a bit rate that cannot be detected by the autobaud mechnism (e.g. 300 baud). Responses to +IPR=0 and any commands on the same line might be corrupted. � See also Chapter 2.2.44. Autobauding and bit rate after restart The most recently detected bit rate cannot be stored when module is powered down (Store bit rate determined with AT&W). Therefore, module will detect bit rate again after restart. SIM300D_AT_V1.00 Page 33 of 180
