First take your local name, in gatttool put:
char-read-uuid 00002a00-0000-1000-8000-00805f9b34fb
in my case show:
handle: 0x0003 value: 45 4c 4b 2d 42 4c 45 44 4f 4d 20 20 20
this value is hex, find in google "convert hex to ascii" to convert it
in my case show:
"ELK-BLEDOM "

You need to know read and write handle in my case my write characteristics is:
handle: 0x0008, char properties: 0x06, char value handle: 0x0009, uuid: 0000fff3-0000-1000-8000-00805f9b34fb

You now need to know at lest ON and OFF commands, in my case 7e0004f00001ff00ef and 7e0004000000ff00ef

With this commands you can try your strip:

sudo gatttool -b be:59:7a:00:08:xx --char-write-req -a 0x0009 -n 7e0004f00001ff00ef # POWER ON
sudo gatttool -b be:59:7a:00:08:xx --char-write-req -a 0x0009 -n 7e000503ff000000ef # RED
sudo gatttool -b be:59:7a:00:08:xx --char-write-req -a 0x0009 -n 7e0005030000ff00ef # BLUE
sudo gatttool -b be:59:7a:00:08:xx --char-write-req -a 0x0009 -n 7e00050300ff0000ef # GREEN
sudo gatttool -b be:59:7a:00:08:xx --char-write-req -a 0x0009 -n 7e0004000000ff00ef # POWER OFF

I receive response: Characteristic value was written successfully and led strip execute the command correct.

You can try to find in google an API with this information , in my case I use:
