I tried another way of reading the rssi value, which gave the following : hcidump -R To which I haven't yet found a proper solution. Get connection info failed: No such file or directory But, even when it was thus connected, I did hcitool rssi the error came like this: hcitool rssi F1:15:A7:E3:17:63

So I tried to anyway at least get one rssi value during the short duration it is connected. I tried keeping the beacons closer, but it did the same. I read here that this is because of poor connections. Then I read that I perhaps need to restart my hci0 by hciconfig hci0 down and then hciconfig hci0 up which did the trick, the beacon now got connected.īut then, it quickly got disconnected after saying `GLib-WARNING **: Invalid file descriptor. So I entered sudo gatttool -b F1:15:A7:E3:17:63 -t random -interactive in which when I gave the connect command, I got error Error: connect error: Device or resource busy (16) and also sometimes Error: connect error: Input/Output Error Then I read I need to use -t random from, and one another source which I can't find right now. Mainly connect error : Connection timed outĪnd Error: connect error: Connection refused (111) This gave different errors after Attempting to connect to , Then I tried with sudo gatttool -b F1:15:A7:E3:17:63 -interactive after which interactive mode opened up and I gave the command connect. Rfcomm connect 0 10 which returned the error Can't connect RFCOMM socket: Host is down when I can be sure hci0 was up.

So next, I again tried connecting with the other two ways: Then connect to one of the beacons using the command hcitool lecc which returned the error Could not create connection: Connection timed out This time I had toįirst do hcitool lescan to get addresses of available beacons Now that I had it for my mobile, I now moved to beacons. Then, I paired my mobile the usual way from bluetooth menu, and then tried hcitool rssi which then finally returned a value -8. In each case, when I clicked pair in my mobile, connection terminated. I thought I need to connect first, so I tried many ways to connect my mobile: To test this, I tried to get it for my mobile first. The best way I could find to get the rssi values was hcitool rssi I have tried most of what I can find on the internet about this: This project is for an RPi, but I am currently trying to test it through my laptop first. I have tried to give as many relevant details as possible. I need to get distances from multiple bluetooth beacons for triangulation so that I can do indoor positioning.
