Hi,

I've programmed CYBLE-012011-00 and CYC4247LQI-BL483 modules with the same "Find Me" program. But with CySmart 1.3 the connection has success only with CYC4247LQI-BL483. 

Why?

Someone can explain me the reasons?

Many tanks in advance

Did I mention ECO cap trims?

One would think that switching target device in PSoC creator it would switch device-dependent parameters. This is not the case and one would be thinking wrong.

The CYBLE-012011-00 requires an ECO cap trim far from the default value given in the example projects.

Go to YourProject.cydwr > Clocks > ECO > Cap trim. Set both values to 17.8 pF.

Of course when you switch back to the CYC4247LQI-BL483 you'll have to reset that.

Note that 17.8 pF is not definitively optimal. See: https://community.infineon.com/t5/PSoC-4/CYBLE-012011-ECO-cap-trim-disagrees-with-KBA/td-p/323688
