MC35i AT Command Set

MC35i AT Command Set4.8 AT+CMUXTable 4.2:Summary of AT commands with Different Behavior in Multiplex ModeCommandAT\QDescriptionIt is recommended to use hardware flow control (AT\Q3). XON/XOFF flow control(AT\Q1) is not supported in Multiplex mode.See note regarding AT\Qn settings stored with AT&W if Multiplex mode is active.AT&V Different default configurations on channels 1, 2 and 3.AT&WAT+IPRAT+IPR=0AT+CALAAT+CMEEAT+CNMAAT+CNMIAT+CFUNAT+CPMSAT^SSDADifferent user profiles can be stored on each channel.Before you start Multiplex mode, it is recommended to set the ME to 57600 bps(minimum should be 4800 bps). For GPRS we suggest to use 115200 bpsor230400 bps.In Multiplex mode, the write command AT+IPR= will not change the bit ratecurrently used, but the new bit rate will be stored and becomes active, when themodule is restarted.Multiplex mode cannot be activated while autobauding is enabled.On each channel an individual message can be stored. but only one timesetting applies to all channels. This means an alarm set on one of thechannels overwrites the time setting on all remaining channels. Therefore, the totalnumber of alarm events returned by the read command AT+CALA? will always be=0, no matter whether individual text messages are stored.When the alarm is timed out and executed the ME sends the URC only on thechannel where the most recent alarm setting was made. The alarm time will bereset to "00/01/01,00:00:00" on all channels.Presentation mode can be separately configured for each channel.If Multiplex mode is activated the +CNMI parameter will be set to zero on all channels,if one channel fails to acknowledge an incoming message within the requiredtime.Phase 2+ parameters can only be used on one channel. The parameter for and on the other channels have to be set to zero. If either a SM or a StatusReport is not acknowledged, all +CNMI parameter will be set to zero on all channels.If the ME is in Multiplexer mode, it is not recommended to activate SLEEP modewith AT+CFUN=. The best approach to properly control SLEEP mode in thiscase is to issue the PSC messages described in [6], Section "Power saving control(PSC)".Parameter will be the same on all instances, but the settings of and may vary on each instance.If one instance is set to =1 and =1, then all other instances must be configuredfor =0.MC35i_ATC_V02.00nConfidential / ReleasedPage 88 of 3909/10/08
