 To upgrade from OpenWRT **22.03.3** to **22.05.0** we used the **sysupgrade** option, which preserves the existing configuration, at least partially.
-Download the new firmware **[[https://downloads.openwrt.org/releases/23.05.0/targets/ramips/mt76x8/openwrt-23.05.0-ramips-mt76x8-tplink_tl-mr6400-v5-squashfs-sysupgrade.bin|openwrt-23.05.0-ramips-mt76x8-tplink_tl-mr6400-v5-squashfs-sysupgrade.bin]]**, connect a PC to one Ethernet port and point your browser to the LuCI web interface. Click the System => ... page and then ... FIXME.
+Download the new firmware **[[https://downloads.openwrt.org/releases/23.05.0/targets/ramips/mt76x8/openwrt-23.05.0-ramips-mt76x8-tplink_tl-mr6400-v5-squashfs-sysupgrade.bin|openwrt-23.05.0-ramips-mt76x8-tplink_tl-mr6400-v5-squashfs-sysupgrade.bin]]** to your PC. Connect the PC to one of the Ethernet ports of the router and point your browser to the LuCI web interface. Click the **System** => **Backup / Flash Firmware** page and then upload the firmware file to the router by clicking **Flash new firmware image**.
 Once the router reboots, you can access it via SSH or LuCI web, the network configuration should have been preserved.
-Beware that all the extra packages must be installed again, notably the **uqmi** package (required to drive the LTE modem for internet access) must be upgraded to version **[[https://raw.githubusercontent.com/mrhaav/openwrt/master/23.05.0/uqmi_2022-11-29-0.11_mipsel_24kc.ipk|uqmi_2022-11-29-0.11_mipsel_24kc.ipk]]**, which is not included into the official repository and thus must be downloaded from the GitHub repository.

+===== Sending and receiving SMS =====
+Once installed the **uqmi** package, there is a daemon process **/usr/bin/uqmi_d.sh** which is responsible for sending and receiving SMS messages. The program will check every 30 seconds if there is a file into the **send** directory and eventually save received SMS messages from the modem memory to the **received** directory:
+  * **/var/sms/send/**
+  * **/var/sms/received/**
+To send a message just create a text file into the **/var/sms/send/** directory; the first line must contain the recipient phone number, the following lines are the text message. E.g.
+<file>
++393274445556
+Hello, World!
+</file>
+Received messages will be saved automatically into **/var/sms/received/**, in files named something like **sms_20240426T150933**. The content will be something like:
+<file>
+[Phone Number|CallerID]
+Tex message.
+</file>
+If you stop the running uqmi_d.sh daemon, it is possibile to retrieve received messages from **sim** or from **me** (memory). Get first the list of messages availables and then retrieve one:
+<code>
+uqmi -d /dev/cdc-wdm0 --list-messages --storage me
+uqmi -s -d /dev/cdc-wdm0 --get-message 0 --storage me
+</code>
