Putting Bluetooth Module Into Low Power Mode

- Aug 25, 2019-

Recently we have been asked by customer about how to put bluetooth module into low power mode.

Customer currently using FSC-BT616 ble module.


1.How to put module into low power mode.

2.Once the device has accepted the low power mode is it possible for it to lose the ability/setting that allows it to get to its low current mode.

3.If we have devices in the field that may not be in low power mode is there anything that can be done using Over the Air Programming to enable the low power mode?
