+===== How can I obtain the EUI from the serial number of my station? =====
-=== How can I obtain the EUI from the serial number of my station? ===
+  * Wirnet iBTS :        7276FF002E<last 6 characters of the CPU serial number>
+  * Wirnet Station :     7276FF000<last 7 characters of the station barcode>
+  * Wirnet iFemtoCell :  7276FF00<last 8 characters of the CPU board serial number>
-  * iBTS :    7276FF002E<last 6 characters of the CPU serial number>
+For the iFemtoCell, you can retrieve the CPU serial number with the following command:
-  * Wirnet :  7276FF000<last 7 characters of the station barcode>
+<code bash>
-  * iFemtoCell :  7276FF0039<last 6 characters of the device board ID>
+root@klk-wifc-01AAFF:~ # grep serial_number /tmp/sys_startup_status.json
+        "serial_number": "0x4501aaff",
+</code>
+In this example, the EUI is ''7276FF004501AAFF''.
+Note you can obtain directly the EUI from the /tmp/board_info.json file:

+<code>

+        "EUI64": "7076FF0054040166",
+root@klk-wiis-040166:~ #
+</code>
+===== What is the maximum number of gateways we can define? =====
   * We can limit the number of gateways, the number of endpoints and number of users linked to a customer via the administration menu (only accessible for users that have SuperAdmin privileges)
-=== What is the maximum number of gateways we can define in the CSV file? ===

+===== What happens when the file embodies a syntax error? =====
   * An exception is raised and the process stops when the error is encountered. All lines located before this point are taken into account by the system
-=== When a mote is removed, is data related to this end-device is also removed? ===

   * No
+===== I have got a frame counter error (FCnt error). What can I do to cancel this status ? =====
+   * In the LNS / endpoint menu, click on your endpoint and then click to the cross at the right side of the text "FRAME COUNTER DOWN"
+   * select F5 for page refresh several times
+=> Status "Uplink ok" appears and uplink message queue is updated with new messages in "Rx messages" tab
+===== What is the VPN subnet address? =====
+When connected to the Wanesy Management Center VPN, the IP address assigned to the gateway is in the ''10.8.0.0/16'' subnet.
+The gateway LAN subnet should not overlap with this subnet.
+===== My external application does not receive any data from WMC =====
+WMC does not follow http redirected URLs. You have to input the real URL.
+To check whether your URL is redirected or not: ''curl -I https://url-example.com/''
+Here is an example of what happens when URL is redirected:
+<code>
+HTTP/1.1 301 Moved Permanently
+Server: nginx/1.12.2
+Date: Wed, 25 Apr 2018 12:56:10 GMT
+Content-Type: text/html; charset=iso-8859-1
+Connection: keep-alive
+Location: http://redirected.url/
+Strict-Transport-Security: max-age=31536000
+Content-Security-Policy: default-src https: redirected.url 'unsafe-inline' 'unsafe-eval'
+x-frame-options: SAMEORIGIN
+X-XSS-Protection: 1; mode=block
+X-Content-Type-Options: nosniff
+Referrer-Policy: strict-origin-when-cross-origin
+</code>
+===== How to put AES keys on WMC ? =====
+AES keys, coded on 32 bits, permit to decode timestamps sent by the stations and used for geolocation.
+Requirements:
+  * Station declared
+  * AES keys known
+Once connected on WMC:
+  - Select menu page LNS > Stations
+  - Filter the station (thanks to its EUI for example)
+  - Access to the station details by clicking on its EUI in the list of stations \\ {{:wiki:step1-2-3.jpg?800|}}
+  - Click on "Add" button. \\ {{:wiki:step4.jpg?800|}}
+  - The below window opens:
+    * Complete RFCH which corresponds to the slot number of the radio modem. Usually RFCH=1. If there are several radio modems: RFCH=2, RFCH=3, RFCH=4...
+    * Put the AES key
+    * Choose its end date of validity \\ {{ :wiki:step5.jpg?400 |}} \\ After AES key declaration, it is possible to check on device RX messages that fine timestamps are well generated:
+  - Select menu LNS > Endpoints
+  - Choose the cluster
+  - Access to endpoint details by clicking on its Dev EUI \\ {{:wiki:steps6-7-8.jpg?1000|}}
+  - Select menu "Rx Messages" and verify that there are fine timestamps from the station \\ {{:wiki:step9.jpg?1000|}}
