wavecom gsm 900/1800 module

Nice library tramp! Do you by any chance sell single unit of SIM300 modules? The inventory page is a bit confusing - it has a price for a single unit but under "package" it says that they come in 100 quantity? (assuming alta-vista translated package correctly :)

Thanks




Thanks bbiandov,
I didnt understand langauge on webpage otherthan engish.I got quotation from a indian distributer for sim300.He quote me $29.5 for 1000 qty.
 

modulo gsm/gprs benq m22 data sheet

hi

does either M22 or SIM300 have SIM card connector integrated on the module or this is something one must figure out using an external molex for the sim card?

thanks

no both modems does not have integrated sim card connectors; you have to add an external one (like Molex 91128)... (do not forget to add also the ESD protection component...)

Hope this helps,

Hi Andrei,

Could you share where does one purchase the Molex 91128 connector and the ESD part suggested on the SIM300 schematic? I looked around but I can't find a supplier. Only large quantity bulk sellers have those part numbers and of course they would not sell a single item.

Also the spec sheet does not make it clear - are the serial ports TTL-level or are they RS232C level shifted?

Thanks
Boyan

OK
Step 3:AT+CIICR

Step 4:AT+CISFR

Step 5:AT+CIPSTART="TCP","www.google.com","80"

I have checked data for my service provider. I instructs to not to set any primary and secondary DNS servers but tells to set primary server to 172.18.19.11 and at port 8080. (I got this instruction using my sim in Nokia 6600). But i dont find any AT command to set these parameter. This IP is probably some Proxy server. Any have any idea how to solve this problem?

P.S.: Sorry for my bad English :D
 

what is mean by c/a in gsm 1800

Hi,
You should use a GSM module of Siemens like MC56, but depends of your application.

If your app is only "data over SMS" then your GSM module should be support only GSM suite (without GPRS if it is possible, I don't know).

But if your app need transfer "data over IP" then you should be adquire only GPRS module. It is no necessary a Module with GSM and GPRS suite.

MC56, G18, G20 are modules with GSM and GPRS suite, then thier cost/ price is more expensive than GPRS module only.
