I bought q24plus a while ago and got it working on my raspberry pi with gammu.
I can send and receive sms messages.
From what I understand now Wavecom is not any more behind these devices.
Now i’m interested on using it
-programmatically over serial port
tried coderzen.blogspot.com/2012/04/se … ython.html
but I cannot get it to work consistently
the message on the phone is displayed as :
SMS over 3G but from Python
where I can find any ref documentation of how to use the embedded tcp/ip stack ?
a hello world example to send/receive sms over serial port
Any help will be highly appreciated
Are you sure that it even has an embedded TCP stack? You might have to do a PPP connection from your RasPi rather than rely on any internal TCP stack.
The Q24 is now quite old and has been obsolete for quite a while.
I notice that there are a lot of these appearing on ebay and even Amazon. Would be interesting to know where they are coming from…
Thanks for quick replay!
Because they are everywhere that’s why I thought they are popular and supported.
To send a message and get an ack from the mobile network takes around 8 seconds.
Can you please recommend the analog on you site which:
- usb gsm module
- with sdk + driver, I want to use it in the project i’m working on to send SMS “but fast”
Sending a message with a phone definitely goes faster, can you give some numbers using your devices ?
All my code is running inside the module (Q26 based) so I don’t have any metrics for sending SMS using a modem as a USB device.
I do know that SMS done as a store and forward and has no guaranteed delivery time - the networks do them as best effort and if the network is busy, the SMS is delayed. My personal best effort is 4 days from sending to when the SMS was delivered! After this effort, I stopped using SMS for delivering alerts and make a CSD phone call instead. Maybe your network is congested?
8 seconds sounds pretty good though.
