Blank Messages bidirectional

[Janssen Vinas Espinoza]

Good Morning

My name is Janssen Viñas, from Costa Rica.

I have a SF800-G unit and I am testing it. I need to send blank messages to Multimodem but it responds the error 621 “Invalid SMS Text”.

I tried through the browser with this HTTP command:
http://192.168.2.1:81/sendmsg?user=test&passwd=xyz&cat=1&enc=0&priority=1&modem=2&to=8888&text=

And the browser responds error 621.

I developed a TCP client C#, and also responds error.
The console manager API, also not accepts blank messages.

What would be the way for process blank messages in the Multimodem.

Thanks…

Hi Janssen,
Currently the API doesn’t allow a completely blank message. Could your application send a message with only a space?

Such as:

http://192.168.2.1:81/sendmsg?user=test&passwd=xyz&cat=1&enc=0&priority=1&modem=2&to=8888&text=%20

This works with the API.

Hi Byron

Thanks for your reply.

I have several prepaid SIM, and one operator only accepts blank messages to check the balance. I tried the last HTTP command, and send the message to the operator, but it returns an error, because it only accepts blanks messages.

When you free up a version that accepts blank messages ?

Please, can me send the last firmware URL. I like to update the core of some Multimodems. I have the version 1.51.25.

Byron other question please ?

I am testing the Multimodem, I need to received SMS from the users. When I send a SMS to the Multimodem, with multipart messages, the Multimodem, divides the messages in several parts. In addition adds some extra garbage characters like “@”.

How I can receive all multipart messages in a single message, and remove the garbage characters such as “@”.

My current configuration is:

• Enable PDU Mode: checked
• Character Set: 3GPP 23.038

Thanks….

Here is an example of the recived SMS:

Jan 1 03:05:39 txrx1-modem: recvlog: [RECV FROM] : 50683155318 : [MSG] : Ich bin Janssen aus Zapote. Meine Arbeit ist programmiert Computer. Ich habe zwölf Jahres wann Programmen. Maine Land ist Costa Rica, das ist eine Land s@

Jan 1 03:05:43 txrx1-modem: recvlog: [RECV FROM] : 50683155318 : [MSG] : chön. Ihren Personen sind gutes. Ich lerne Deutsch und Englisch Sprachen.@

Hi Janssen,
I’ll look into making changes to allow sending API messages with blank text messages.

To send multipart messages as one long message, you must have both “Enable PDU Mode” and “Concatenate Multipart Outbound Messages” enabled.

The extra @ characters on received multipart messages is a known bug that was fixed in v1.51.28. Please see links below.

SF100 v1.51.28:

SF400 and SF800 v1.51.28:
