Hi I am looking for references and best solution for rabbit online firmware upgrade using ethernet. I use 3720/3700 modules. Ready to purchase if get good...
Hi there, I am trying to send an SMS once a GPRS connection has already established. In fact SMS will contain GPRS IP, so cannot stop and restart GPRS...
Pankaj, I've used Scott Henion's downloader for a few years and it works great. It's simple, easy to use, and reliable. It's also cheap -- $125. You can find...
Using only AT commands I get a bunch of bytes followed by a "NO CARRIER" message. After that GPRS connection is lost. Anyway I need to establish an IP...
There may be another way to achieve this. Modems have hardware handshake lines. I cannot remember which one, but de-asserting it will also suspend the GPRS...
Dear Rabbit Community, I'm starting a project based on the RCM4400W core module. I plan to have it finished by February. Please feel free to visit the blog at...
Have not used your particular equipment but in Hayes compatible equipment (Hayes defined the AT command set) the S12 register sets the guard time. The guard...
Thanks everyone. I looked up the suggested parts, and Maxim parts do seem a bit difficult to come by. And they don't seem to be cheap either. Can anyone think...
First of all, thanks for helping Alexis :-D. I had also taken a glance to that way, but I had read it is only possible to stop GPRS connection using DTR or DSR...
... What kind of precision do you need? May I suggest something like an ATTiny26? Not a dedicated A/D, but you can do 8 channels, 10 bit and run serial....
... Yes, I have been tempted to use a PIC controller (a bit more $ for precision.) But would use a simple serial interface instead of SPI/I2C. I have used them...
If your application is large or small, cool or routine, we want to hear about it. We are collecting submissions for use in our Rabbit eNews Update and the...
I have got to say my experience of Maxim is very good. In fact they are quite generous people. You can order FREE samples from there website if you just need...

Hi, Some remarks: as far as I know, the Wavecom modules cannot be used to send SMS while connected via PPP. Therefore you need to tear the PPP connection down...
The +++ approach is very slow. There is a way to use a control line to switch the modem into command mode (this may be something you need to configure but I...
It is possible to get the GSM/GPRS provider to setup a private GPRS network for you. This removes the firewalls etc. We have done this with some telemetry...
The solution with a private APN is not portable (I mean, should your devices need to be used on several GSM networks, e.g. in more than one country) and...
Hi folk, i have implemented web server and there are two pages, say login page (index page) and show.html. I use on CGI function to validate the user id and...
In our case it was for the one client with all GSM devices on a corporate account. We have also done the push approach as well. In the end of the day it all...
Hi Using the AT commands as I suggested allows one to open a GPRS session. The session can be suspended and an SMS can be sent. Thereafter the GPRS session is...
Hi all again, Even though I've really not going deep into it, looks like you are right Alexis. But I fear I need the ppp.lib because of the RCM3200 acting as...
Hi I don't know the answer to this, but do you need the PPP lib to run all those features? Surely the PPP lib just encapsulates the data? Maybe someone more...
The problem is when using libraries such snmp.lib, which expect an interface to be established to get and set data through. I guess it would be possible to map...
In order for your plan to work (escape to command mode with +++), you need to make sure that nothing calls tcp_tick() (or any other function that calls...
I haven't dealt with the PPP library in a while, but I thought it grabbed the interrupt and didn't let go when ifdown-ed. And, the PPP library wasn't too...
