As flespi can get into work as soon as device connects to your channel’s IP:port you need to make sure that device can reach it. 

As soon as a new connection appears in the flespi channel, you will see the appropriate log in channel Toolbox:

If you don’t see any logs in your channel, your device didn’t reach your flespi channel IP:port. Therefore, neither flespi nor flespi team can help you. Following is the checklist to verify all parts of the chain before data gets from the tracking device to flespi:

Hardware

1. The device has the power supply.

2. SIM-card is installed.

3. All required sensors and antennas are connected.

Internal logic

4. Depends on the device: some devices must have GPS signal to start sending data, unlocked with some program-tools, somehow activated etc. Check the documentation.

SIM-card

5. SIM-card has a positive balance and the plan allows using the Internet.

6. APN settings are set (may be set up from flespi device configurator via SMS).

GSM carrier

7. Carrier provider does not block access to flespi IP address (see subsections about SIM card below).

You might think that the problems are on the flespi side, but we can assure you that flespi is up and running.

How to check that SIM-card can connect to flespi

To check that the problem is on the device layer and connectivity issue is caused by the tracking device itself but not by SIM-card problems or GSM carrier settings you may do the following:

1. Insert SIM card in the smartphone.

2. Install any application that can open connection to the desired IP:port. E.g. telnet (iOS, Android).

3. Test if the smartphone can reach your IP:port by checking the appropriate log in Toolbox.

How to check that SIM-card can receive SMS from the flespi modem

In the same way, you can test if the flespi modem can send SMS to your carrier (some carriers may block SMS from outside the country). Send any setting via SMS from device configurator tab while SIM card is inside the phone. If you don’t receive any message, it might be blocked by your carrier. Having your own SMPP modem that can work in your country often helps.
