For proper operation of the CC3130 device, perform the recommended power-up sequencing as follows:
- Tie the following pins together on the board:
- VBAT (pins 37, 39, and 44)
- VIO (pins 54 and 10)
- Hold the RESET pin low while the supplies are ramping up. TI recommends using a simple RC circuit (100 K ||, 0.01 µF, RC = 1 ms).
- For an external RTC, ensure that the clock is stable before RESET is deasserted (high).
