getWaitingMessageCount returning wrong int

[David Ahrens]

I know there is a message waiting however the following return 0
int nummessages = modem.getWaitingMessageCount();
Serial.println("Message count from satellite: " + String(nummessages));

Diagnostic data stream...

AT+SBDIX
Waiting for response OK

<< ..AT+SBDIX................
+SBDIX: 0, 0, 1, 1, 11, 0

OK
SBDIX MO code: 0
SBDIX success!
Message count from satellite: 0

@infinitemind2,

According to the guide at

http://www.rock7.com/downloads/IRDM_ISU_ATCommandReferenceMAN0009_Rev2.0_ATCOMM_Oct2012.pdf

the message count is the sixth number after the "+SBDIX:" in the return string.

From the docs:
Command Response:
+SBDIX:,,,,,

In your example, this is 0, so I think the Iridium system does not think there's a message waiting.
