By instructing sendfile() to send the whole content of the assistance data at once results in a big data transfer (> 4kb) first followed by a huge amount of small transfers (64 or 128b). This "overloads" the modem which needs to process smaller chunks of data and have more time to do so (experimentation shows that 1kb need 100ms for processing, or the upload will subsequently fail). This commit sets the transfer size to 256b and increase the timeout between each transfer to 25ms.
eg25-manager - Quectel EG25 management daemon
eg25-manager is a daemon for managing the Quectel EG25 modem found on the
Pine64 PinePhone.
It implements the following features:
- cleanly power on/off the modem
- configure/check essential parameters (such as the audio format) on startup
- monitor the modem state through ModemManager
- put the modem in low-power mode when suspending the system, and restore it back to normal behavior when resuming
- monitor the modem state on resume and recover it if needed
Dependencies
eg25-manager requires the following development libraries:
- libglib2.0-dev
- libgpiod-dev
- libmm-glib-dev
Building
eg25-manager uses meson as its build system. Building and installing
eg25-manager is as simple as running the following commands:
$ meson ../eg25-build
$ ninja -C ../eg25-build
# ninja -C ../eg25-build install
Configuration
eg25-manager uses device-specific configuration files, named after the
device-tree compatible field. These files are installed to
/usr/share/eg25-manager. They can be copied to /etc/eg25-manager then
modified, that way they won't be overwritten during an upgrade.
Running
eg25-manager is usually run as a systemd service, but can also be
manually started from the command-line (requires root privileges):
# eg25manager
