Current implementation uses a gpio level of 1 for powering on quectel modems using a gpio and a level of 0 for powering off. Normally quectel modems are powered on or off by a gpio pulse on their PWR_KEY pin. They turn on by the first pulse and turn then off by the next pulse. The pulse length varies between different modems. For power on the longest I could in the quectel hardware is "more than 2 seconds" from Quectel M95 Hardware Design Manual. For Quectel EC21 this is ">= 100 ms". For Quectel MC60 this is "recommended to be 100 ms". For Quectel UC15 this is "at least 0.1 s". For power off the four modems in question vary between a minimum pulse length of 600-700ms. This implements a 2100ms pulse for power on and 750ms for power off. If you have some special circuitry that powers your modem by gpio level and you need the old behaviour, you can switch to gpio level powering by setting environment variable OFONO_QUECTEL_GPIO_LEVEL. The gpio goes to high level for the modem to power on and to low level if it should power off. |

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. Information =========== Mailing list: ofono@ofono.org For additional information about the project visit oFono web site: http://www.ofono.org
