Hello;
I had a circuit with msp430f2481 and a BLE112(cc2540 wit 8051) module.Communication between the two modules is done through UART.so far so go,my module works fine.
but for reasons of consumption we had to add a TPS62730 module to reduce the current consumption during TX/RX. but after modification we have many problem of disturbance in my UART frame receive in my mps430 causing a malfunction.
you have an idea what can cause disruption you have an idea what can cause disruption TPS62730 ?
and there is a special assembly to avoid such disruption?
Thank you
