ofono with sim5320 module
by David Ashley
Hello, I'm at my wits' end trying to get ofono working with the
sim5320 module. I'm using the plugins/sim900.c module as a starting
point. I think the issue has something to do with the difference
between the MUX functionality between the 900 and the 5320. The sim900
supports the elaborate parameters sent on the
AT+CMUX=0,x,x,x,x, etc.
but the SIM5320 only supports
AT+CMUX=0
There's that... but also the way the sim900 plugin creates a
SETUP_DLC, initiates muxing, then deletes the setup DLC and creates 4
new DLC's... it didn't work for the sim5320 until I remapped the DLC's
somewhat like this:
#define NUM_DLC 4
#define VOICE_DLC 2
#define NETREG_DLC 1
//#define SMS_DLC 2
#define GPRS_DLC 3
#define SETUP_DLC 0
static char *dlc_prefixes[NUM_DLC] = {
[VOICE_DLC]="Voice: ",
[NETREG_DLC]="Net: ",
// [SMS_DLC]= "SMS: ",
[GPRS_DLC]= "GPRS: " ,
[SETUP_DLC]= "Setup: ",
};
Note I have to eliminate the SMS_DLC usage later in sim5320_post_sim:
// ofono_sms_create(modem, OFONO_VENDOR_SIMCOM, "atmodem",
// data->dlcs[SMS_DLC]);
OK everything is *ALMOST* working. ofonod interacts fine with
connmand, connmand tells ofonod to activate the sim5320, which
actually establishes a ppp connection and sets up a ppp device:
ppp0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-0
inet addr:30.97.132.47 P-t-P:30.97.132.47 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:2 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:500
RX bytes:0 (0.0 B) TX bytes:124 (124.0 B)
Here's the rub: No matter what I do, I never get any RX packets from
that ppp device, and even when it appears to TX packets (I'm trying to
ping out) the machine on the internet isn't actually receiving them.
I'm running on a beaglebone with a custom board with a sim5320 module on it.
I have no idea what to try... Any advice would be appreciated...
Thanks very much!!!!

HFP HF - Reject SCO Issue
by Jomon John
Hi,
I am trying to configure HFP with Bluez(5.34), Ofono(1.17) and pulseaudio(6) on a Freescale i.MX6 board using Linux 4.1.15 kernel, the idea is to use the target board in HFP/Handsfree Unit role. The bluetooth controller is a Pluggable USB Bluetooth Dongle (0a5c:21e8 - BCM20702A0) with updated firmware.
The procedure followed is,
* Pair & connect with the android mobile phone with the bluetoothctl
* Enable modem and dial number using ofono test scripts
After this the call is being made but the audio routing fails with "Reject SCO : Agent not registered" message from oFono. While checking with btmon its found that the SCO Connect Request has been rejected with the reason of limited resources(0x0d).
Can anyone help me to identify the root cause, I spent a lot of time trying different version combinations, loading firmware and checking logs but still nothing.

ofono resume problems
by Enrico Sau
Hi all,
I'm having a problem with AT channel in ofono and I don't understand why.
Steps:
- start ofono
- enable modem
- do stuff
- quit ofono
- enable modem again
At this point I got no answer from the first sent AT message (log is
attached).
I believe is a modem problem but I need to understand what is happening.
Does ofono close file descriptors on shutdown?
Thanks for any thoughts!

read phonebook
by Marco Trapanese
Hello,
I have this setup:
- RPi3
- Raspbian Jessie Lite
- bluez 5.40
- ofono 1.18
in /etc/bluetooth/main.conf I set this class: 0x640408.
Using bluetoothctl I connected my phone to the SBC and I can make a call
using the ofono tests.
I wonder how to read the contacts. I launched test-phonebook but I got
this error:
> Method "Import" with signature "" on interface "org.ofono.Phonebook" doesn't exist
Do I need to enable something other before?
Thanks
