10.6 AT^SISW Internet Service Write Data
AT^SISW write command triggers writing data via the Internet service configured configured with AT^SISS.
MC55 returns the amount of data which can be written:
• <cnfWriteLength> value equal 0 indicates that the MC55 failed to enter online data mode. Details about
the cause of failure is available using AT+CEER.
• <cnfWriteLength> value greater than 0 indicates that the MC55 switches into online data mode to transfer
the given number of bytes.
A URC "^SISW: <srvProfileId>, <urcCauseId>" will be issued if
• the MC55 is capable to send data after opening the Internet service or
• less transmission buffer space was confirmed (in <cnfWriteLength>) than requested (with <reqWrite-
Length>) or
• or all available data have been transferred.
This mechanism is designed to avoid polling for free transmission buffer space and thus, free the TA for other
tasks.
