Hello,

how do you send a specific configuration to the cellular phones (Nokia, SonyEricsson)? There is a standard protocol for this? And is it open?

I know that all configurations can be send via SMS and if possible, I want to implement something for it. Because here in Brazil we are trying to configure some Gradiente cells using the NowSMS software and there is no success.

Thanks in advance,

Marcelo Muzilli

Hi Marcello,

Not all phones can be configured OTA (but this situation is improving).

In NowSMS, we support two primary types of OTA for configuring phone settings.

What we refer to as "WAP OTA", is OTA according to the Nokia/Ericsson WAP OTA Specification. You can download a copy of this specification from the SonyEricsson developer web site (www.sonyericsson.com/developer). Practically every phone with a WAP browser that has been released by Nokia or (Sony)Ericsson has supported this ... except that some newer Nokia phones have moved on to the specification that I'm about to describe.

What we refer to as "OMA OTA" is OTA using OMA Provisioning Content, as published by the Open Mobile Alliance. This specification can be found at http://www.openmobilealliance.org/tech/affiliates/wap/wapindex.html.

Both of these formats are XML based, and then they get encoded into a binary format for transmission over SMS.

If you use the "Send XML Settings" option in NowSMS, you can send either of these types of documents, and NowSMS will perform the binary encoding, so you can do some experimentation if necessary.

Some simple examples of the XML formats can also be found here:
