i already connected 2 devices using hc 05...so i already use at-command to configure it into master and slave mode... My idea was to make the master device vibrate if the slave device move away for a certain distance...anddddd now, im stuck..someone said we can use rssi to get the value in HEX.. I tried using the AT+inq but its said "error(1F)".BTW sorry, im not so good in english
Won't work. HC05 is "buggy", to put it in nice words. Inquiry does not work reliable - if it works at all.
The RSSI value is almost always useless for determining distance, because other factors (absorption, interference, antenna orientation) affect RSSI more strongly.
I submit the best you can expect with the HC-05 is to check whether the slave is simply in or out of range, i.e. monitor the status LED, perhaps. There is nothing buggy about the HC-05 but it is a plain vanilla BT2 device, just good for SPP data transmission. IF you really want to pursue RSSI, after reading reply #2, twice, you would be a bit better off using a BT4 device like the HM-10 rather than a BT2 device.
Your english is fine for the purpose - not a wanna or gonna to be seen, which is more than can be said for the president of the United States.
Yes, very sad.
Some times I am glad that I am an old man and near the end of the road.
In a few more years we will have a society that converse like 13 year old girls on Twitter.
It amazes me that people can't even use the spell checker when posting.
