I am using BCM920737_LE_Kit as a BLE central & interfaced it to the other MCU trough UART , Also i interfaced two sensors to Central device(Resistive Force Sensor as ADC i/p On pin P11 ,Shock Sensor as a External Interrupt on Pin P3 ). I am collecting data from the WICED sense tag as a peripheral device(Temp,Humidity & Press) adding force value to packet i am sending it over PUART (P32,P4-as PUART TX,RX).
When ever i give shock interrupt the force value get changed automatically.Also other temp & press values also changes..OR sometimes board itself RESTARTS .
Or even i change VTG on pin P11(ADC I/p force sensor) the other pin vtg get changed ...
I tried on USB power mode & Battery Mode also ..
I am using external power supply of 3.3v for Force & shock sensor ..Did proper GND connection also..
I thick the board have Power issue..
I want that when i trigger interrupt on P3 it should not cause any change on ADC & other pin vtgs..
Also When the ADC i/p Vtg changed it should not change other pin voltages.
