st=fail since mysensors 1.5.4 update

[mrcrabs]

Hi !

It's my first post !

I've a mysensors network with 2 repeaters, 4 nodes ; and I noticed a problem since I updated my nodes to mysensors 1.5.4 ;

Since reflashing nodes, I have a lot of st=fail in my logs, and data doesn't reach the gateway.

After doing some tests, my conclusion is that the gw.send command sends too quick the data.....

I fixed that behaviour by adding the gw.wait(200) command after each gw.send(...).
Since I've done that on all my nodes, the problem disappeared !

I don't know how it can be possible ????

Sincerely,

I didn't told you : I've decoupling capacitors on all my nodes. My gateway has a separate 3.3V regulator since it as an amplified NRF24L01+ with an external antenna.
