Hey,
my Asterisk got a problem with the chan_dect module.
I build it like it's written here:
http://dect.osmocom.org/trac/dect/wiki/Build%20instructions
debian*CLI> module load chan_dect
Unable to load module chan_dect
Command 'module load chan_dect' failed.
[Aug 10 14:23:41] WARNING[19284]: loader.c:449 load_dynamic_module: Error
loading module 'chan_dect': /usr/lib/asterisk/modules/chan_dect.so:
undefined symbol: dect_mm_endpoint_get
[Aug 10 14:23:41] WARNING[19284]: loader.c:839 load_resource: Module
'chan_dect' could not be loaded.
Could someone help me, getting this fixed?

Ok thank you a lot Patrick.
Here are the results:
with your last patch:
dect-transceiver-list --name trx0
DECT Transceiver trx0@cell0:
Type: vtrx
RF-band: 00000
Events: busy: 0 late: 0
slot 0: <scanning> packet: P00 carrier: 27 (0.000 MHz)
RX: bytes 0 packets 0 a-crc-errors 0 x-crc-errors 0 z-crc-errors 0
TX: bytes 0 packets 0
*The frequency is always 0 MHz*
The kernel logs seems to be OK:
[15122.889144] vtrx trx0: set carrier: slot: 0 carrier: 23
[15122.899150] vtrx trx0: set carrier: slot: 0 carrier: 24
[15122.909150] vtrx trx0: set carrier: slot: 0 carrier: 25
[15122.919151] vtrx trx0: set carrier: slot: 0 carrier: 26
[15122.929150] vtrx trx0: set carrier: slot: 0 carrier: 27
So I have tried your last patch with mine to force the rf_band to 1:
dect-transceiver-list --name trx0
DECT Transceiver trx0@cell0:
Type: vtrx
RF-band: 00001
Events: busy: 0 late: 0
slot 0: <scanning> packet: P00 carrier: 23 (1921.536 MHz)
RX: bytes 0 packets 0 a-crc-errors 0 x-crc-errors 0 z-crc-errors 0
TX: bytes 0 packets 0
The channel seems to be ok, but no station are visible during scanning…
My contact in USA is not present, perhaps he is not at home… do not know if its station is on...
About trx2:
dect-transceiver-list --name trx2
DECT Transceiver trx2:
Type: sc1442x
Features: slow-hopping,p64
RF-band: 00001
Events: busy: 0 late: 0
slot 0: <idle>
RX: bytes 0 packets 0 a-crc-errors 0 x-crc-errors 0 z-crc-errors 0
TX: bytes 0 packets 0
(no a-crc-errors)
If I remember well, with only my patch which forces the rf_band to 3 we got for trx2:
dect-transceiver-list --name trx2 I see that slot0 is scanning:
DECT Transceiver trx2@cell0:
Type: sc1442x
Features: slow-hopping,p64
RF-band: 00003
Events: busy: 0 late: 0
slot 0: <scanning> packet: P00 carrier: 5 (1888.704 MHz)
RX: bytes 0 packets 0 a-crc-errors 1629 x-crc-errors 0 z-crc-errors 0
Hello,
I am trying to use a dosh&amand PCI card… this one:
01:03.0 Communication controller: Quicklogic Corporation COM-ON-AIR Dosch&Amand DECT (rev 32)
Subsystem: Device 1786:0001
Control: I/O- Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx-
Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
Interrupt: pin A routed to IRQ 20
Region 0: Memory at ddefe000 (32-bit, non-prefetchable) [size=8K]
Kernel driver in use: com_on_air_pci
with the dect kernel stack…
I have managed to compile the kernel 3.2.0 with this config:
CONFIG_DECT=m
CONFIG_DECT_DEBUG=y
CONFIG_DECT_CSF=m
CONFIG_DECT_RAW=m
CONFIG_DECT_CCF=m
CONFIG_DECT_LU1_SAP=m
CONFIG_DECTDEVICES=y
CONFIG_DECT_VTRX=m
CONFIG_DECT_COA_PCI=m
CONFIG_DECT_COA=m
CONFIG_DECT_COA_U2785=y
CONFIG_DECT_COA_FIRMWARE=y
CONFIG_DECT_COA_P64=y
The driver seems to work but the issue is that I am trying to use it in USA for an American client, and I did not managed to make this card use the 1.9Mhz band (rf band 3 I guess).
When I run this command:
dect-transceiver-list --name trx2 I see that slot0 is scanning:
DECT Transceiver trx2@cell0:
Type: sc1442x
Features: slow-hopping,p64
RF-band: 00003
Events: busy: 0 late: 0
slot 0: <scanning> packet: P00 carrier: 5 (1888.704 MHz)
RX: bytes 0 packets 0 a-crc-errors 1629 x-crc-errors 0 z-crc-errors 0
but it nevers uses RF band 3 channel.
For you information I have patch the driver this way to set the default debt rf band to 3:

Is there anyone available for hire to help me get Dedected like CLI
tools working with OcmocomDECT. I have the Com on Air PCI card and
can't figure out how to get the driver to work. I need some guidence
and willing to pay for it.
Please advise,

Hello List,
I'm new to the osmocomDECT project and just bought 2 com-on-air PCI Cards.
After reading the list archive, i have some questions about the state of
the project.
What features do we suport at the moment?
Can i build a dect cell with asterisk support?
is handover within a cell about multiple basestations supported?
if i can help, test or support the project with hardware, so please tell ;)
