uBlox devices present their USB interfaces well before those interfaces are ready to respond to any commands. The documentation says to monitor the 'greeting text' to detect readiness, but this 'greeting text' is not actually specified for any device other than the TOBY L4. What seems to work is to probe the device with 'AT' commands until the device responds, and then to wait an additional second before proceeding. The TOBY L4 reliably sends its 'greeting text' (+AT: READY) within this interval. It would be more rigorous to actually wait for the 'READY' indication for the TOBY L4, but that would require knowing the device model before the device model is actually queried. This is doable via the USB product ID, but overkill when the above heuristic seems to work reliably. Before this patch, the ublox plugin was trying to achieve something like the above with the g_at_chat_set_wakeup_command() function, but that had some issues: i) it did not work reliably, in particular failing badly on the TOBY L4 with responses getting out of sync with commands ii) it was an inappropriate use of the wakeup_command which is intended for devices that may sleep when there is no communication during some interval This patch adds an init sequence that probes the device for readiness before continuing with initialization. |

oFono - Open Source Telephony ***************************** Copyright (C) 2008-2011 Intel Corporation. All rights reserved. Compilation and installation ============================ In order to compile telephony stack you need following software packages: - GCC compiler - GLib library - D-Bus library To configure run: ./configure --prefix=/usr --mandir=/usr/share/man \ --sysconfdir=/etc --localstatedir=/var Configure automatically searches for all required components and packages. To compile and install run: make && make install Embedded Linux library ====================== In order to compile the daemon and utilities the development version of Embedded Linux library is required to be present. The development repositories can be found here: git://git.kernel.org/pub/scm/libs/ell/ell.git https://kernel.googlesource.com/pub/scm/libs/ell/ell.git The build systems requires that the Embedded Linux library source code is available on the same top level directory as the source code: . |--- ell | |--- ell | `--- unit `--- ofono |--- src `--- tools It is not required to build or install Embedded Linux library. The build will happen when building the Wireless daemon and it will then be linked internally. When using --enable-external-ell build option, it is not required that the Embedded Linux library source code is available in the top level directory. Kernel Dependencies =================== In order to have the PPP stack working in oFono you need to enable CONFIG_TUN (Universal TUN/TAP device driver support) in your kernel .config.
