As flespi can get into work as soon as the device connects to your channel’s host: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 the channel Toolbox:
If you don’t see any logs in your channel, your device cannot reach your flespi channel host:port. Therefore, neither flespi nor the flespi team can help you. Following is the checklist to verify all the links in the chain before data gets from the tracking device to flespi:
Hardware
The device has a power supply
SIM-card is installed
All required sensors and antennas are connected
Internal logic
Depends on the device: some devices must have a GPS signal to start sending data, be unlocked using a certain software tool, somehow activated, etc. Check the documentation carefully
SIM-card
SIM-card has a positive balance, the plan allows using the Internet, SIM-card is not locked by PIN-code
APN settings are set (maybe set up from the flespi device configurator via SMS)
GSM carrier
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:
Insert SIM card in the smartphone
Install any application that can open a connection to the desired host:port. E.g. telnet (iOS, Android)
Test if the smartphone can reach your host: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 the device configurator tab while the 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.
