OLGA Communication Trouble Shooting

The red LED status provides feedback very quickly as to the basic communication status of the OLGA unit.

This is the very first thing that should be checked!

Red LED never turns on

This means there is no power to the unit

1. Check the cable is plugged in
2. Check the fuse
3. Try a different cable as the cable may be damaged

Red LED comes on and stays on

This means there is power to the unit, but is unable to get onto the mobile network. Basic checks are:

1. Make sure a SIM is inserted correctly
2. Make sure the SIM retaining switch is properly engaged
3. Make sure the unit has an antenna attached

If all of the above checks out OK, then further checks are needed:

4. Make sure the SIM retaining switch is not damaged
5. Make sure the antenna connection for the unit is not damaged
6. Make sure the antenna is not damaged
7. Try cleaning the SIM and putting it back in
8. Does the SIM popup in / out OK or has the SIM holder been damaged
9. Try a different SIM that you know works

If all indications are that the unit should work and if everything appears to fail and the red LED stays on permanently, the OLGA unit’s antenna is most likely to be damaged internally from over-tightening. The unit should be returned to BeTree for scrapping as the unit is unrepairable.

Red LED comes on occasionally and after a while goes out and stays out

This is an indication of corrupt flash. This is sometimes repairable and if within the warranty period is repaired or replaced free of charge.

Red LED flashes like mad

This indicates a hardware error and is covered by the warranty period.

Red LED comes on and after a short while starts flashing about once every second

This is normal behaviour when the OLGA unit’s SIM has detected a mobile network. However, this does not mean it is able to communicate as there are other factors needed for communications to occur. Advanced trouble shooting is needed if communications do not appear to be happening:

With advanced trouble shooting; the unit should be attached to a computer with a serial port in order for testing and a firmware update using the OLGA Firmware Update application which is free to download from the website.

1. The first thing that should be done is to update the OLGA unit firmware to the latest version. This in itself may clear the problem. So, update the firmware and retest. If the OLGA unit already has the latest firmware version the please skip this step.
2. Use the OLGA mobile webpage www.olgaonline.co.uk/olgamobile.aspx to determine if the OLGA unit is sending logged data. Any data that is logged is sent in chronological order so it may well be sending logged data until such it’s caught up to the live data. The communication date and time will change about once every 5 minutes if logged data is being transmitted, and so can take some time to push through.
3. Make sure the APN for the unit is OK for the SIM you’re using. If your SIM is using a specific private APN then the OLGA unit needs this setting.
4. Check the signal strength. It may be the antenna is partially damaged internally causing extremely low signal strength. If this is the case the unit should be sent back to BeTree for scrapping as the unit is not repairable.

Sending units back to BeTree

Any unit that has a damaged internal antenna, or is damaged beyond repair should be sent back to BeTree for disposal, which is free of charge. Any further data storage charges are subsequently removed.

Units that have a broken SIM retaining switch can be repaired for £20 + P&P per unit; and any repaired unit has the firmware updated.

Any units that are returned which are not faulty have the firmware updated and returned at a cost of £15 + P&P per unit.

Any units that require re-flashing under warranty is either repaired or replaced free of charge. Out of warranty units that are repaired by re-flashing are done so at a cost of £20 + P&P per unit. Out of warranty units that cannot be repaired require disposal which is done free of charge.
