Data exchange on Mesh network not stable

In Point to Point systems we are sending data and the data flow is perfect , no queries . But when we install Mesh Firmware, we are having the following problems

  1. Data loss if found
  2. Junk data is transmitted
  3. Delay is also seen . This is seen only during Mesh and not during P to P .

¿ How many nodes are you using in your test?

If you have a Point to point communication why do you need a mesh ?
