⚠️ Common set-up errors - Please check before commissioning! – Brevis.one

To ensure smooth operation of your device, please consider the following points before commissioning:

1. 🔒 Disable SIM PIN Protection

Issue: The device cannot establish a cellular connection or crashes unexpectedly.
Cause: The SIM card is protected by a PIN code.
Solution: Disable the SIM PIN protection before inserting the SIM card into the device. This can usually be done via the settings of a mobile phone.

2. 📶 Insert SIM Card Correctly

Issue: No network connection is possible.
Cause: The SIM card was not inserted correctly.
Solution: When inserting the SIM card, ensure it clicks firmly into place. A distinct clicking sound confirms proper insertion.

3. 🕒 Configure NTP Time Server

Issue: Time mismatches between system time and actual time can lead to certificate errors, connection issues, or incorrect log data.
Solution: After the device's first boot, configure an NTP server to automatically synchronize the system time.

4. 📡 Check Mobile Signal

Issue: No network registration or communication is possible.
Cause: Poor signal reception due to unsuitable antenna positioning or location.
Solution:

Position the antenna closer to a window or move it outside to improve reception.
Check the signal strength in the device’s web interface under "Modem Status".

5. 📡 Set the APN

Issue: The device is registered in the network but cannot send SMS.
Cause: Missing or incorrect APN entry under "Status" > "Modem Status". SIM card is not SMS-enabled or not activated.
Solution:

Set the correct APN under "Status" > "Modem Status". You can find the correct APN online or obtain it from your mobile provider.
If you're unsure whether your SIM card is activated, insert it into a mobile phone and check its status, or contact your provider.

⚠️ Note: An incorrect APN may cause the device to crash or reboot unexpectedly.

6. 🛜 Gateway Not Reachable on the Network

Issue: After a restart, the gateway loses its IP address or becomes unreachable.
Cause: Temporary IP was set via the console. No DHCP server is active. Default gateway is undefined.
Solution:

Set a temporary IP address along with subnet and default gateway using a console cable and a terminal program such as PuTTY.
Then, assign a static IP address via the web interface under "Configuration > Network".
