Hi Manoj,

With a 3.6 V battery, please ensure your jumper settings are set for <5 V operation on the EVM.

The battery should be connected to BAT+ and BAT-, as shown in the EVM User's Manual.

Also, please make sure that you connected the wires on the EV2400 to the I2C port, and to the I2C port on the EVM. Do not use HDQ for bringup.

Sincerely,
Bryan Kahler
