I am running a project using a thermistor. I started by using the evaluation board as shown:

The program runs fine. After that, I removed the module from the evaluation board and powered the module using an external power source (3V).

I moved the resistor and thermistor from the evaluation board from the pins [3.0 - 3.1 - 3.2] to the module to the pins [3.0 - 3.1 - 3.2] on the BLE module it self (same numbering for the pins). I powered up the module it shows up on the phone app with the same project name.

In this state, the chip is pulling ~1mA in sleep mode.

However, when I try to connect to it and click on the project icon, the temperature is fixed on zero and if I go back the module does not show up on the Bluetooth search until I restart it again. the current pulled by the chip is zero after it disconnects.

(Note: I did not change anything on the PSoC creator or the code, I only transferred the resistor and the thermistor)

I feel it is a pin connection issue, but I don't know which pin is it. Any ideas!
Note: I was following the example here: https://github.com/Infineon/PSoC-4-BLE/tree/master/100_Projects_in_100_Days/Day005_Health_Thermomete... )
