hi i am beginner i am trying to implement bump mapping with vbo and glsl. My question is: did i make bump mapping ? if i did why these edges didnt disappear ?
high and low meshes (i used low meshes of course)

That's not how bump mapping works. Bump mapping adds additional detail to a model, but doesn't change the triangles. You need to render a mooth mesh to make the edges invisible (the normals of a vertex shared by 2 triangles must be the same)

\$\begingroup\$ Additionally the mesh could make use of some smooth shaded normals. But yes the normal map only operates on the faces themselves. \$\endgroup\$ – Sidar Mar 27 '18 at 6:32

\$\begingroup\$ so i did right ? but this video seems perfect with not smooth low mesh youtu.be/ApzVWuPa4A4?t=1113 \$\endgroup\$ – Emre Kaya Mar 27 '18 at 6:46

\$\begingroup\$ @EmreKaya your model is showing flat shading, you might want to adjust the the normals. Notice how the faces all show rigid along the edges? \$\endgroup\$ – Sidar Mar 28 '18 at 14:48
