NOKIA 61xx and infrared communication - one phone
The noks use two different kinds for communication over infrared
The ncds-protocol over infrared (or
shortly: ir) is not irda-compilant!
Only the protocol between two
noks or a nok and a printer over ir is irda-compilant!
a) IrDA-compilant transfer
Noks of kind 61xx can exchange datas between two phones. This datas are
If you transmit this kind of data between phones the following way is used:
If you print a shortmessage or a phonebook-entry from phone to irda-printer
the way defined in IrCOMM is used after connection establishment.
sending phone make discovery
receiving phone answer to discovery
speed is switch to 115200 bps
sending phone ask with GetValueByClass from IAS in IrLMP for N o
k i a : N B S r o
u t e r
(NBS is Narrow Band Socket)
receiving phone answer with LSAP-SEL for NBSrouter
establish NBSrouter-connection into IrLMP-Layer
exchange the datas over nbs and smartmessaging
b) NCDS Transfer
The ncds use a nokia-specific-protocol between the pc and the phone. The
protocol over serial cable and infrared is the same. For connection establishment
over infrared the following way is used:
You can find the details of this protocol on the website of gnokii - or
better: in the source-code. Gnokii is a nice linux project what works as
the ncds under linux - or: Gnokii works better and has more features
as the original NCDS for windozen! You can find gnokii project under: http://multivac.fatburen.org/gnokii.
