Hi ,

our project is runnin on nrf52840 , and we need to add WiFi ability .

I am thinking to use CYW4343W as combo cotrollerless WiFi and BLE solution .

Our requirement operation mode are :

1) sleep mode + BLE peripheral  advertising every 1 Sec less than 1mA

2) Operation mode 30mA + BLE peripheral advertising + reading sensors + save to memory 64MByte

3) Charging mode + Wifi ability to stream the memories Less than 3 Min

My question are :

* is this possible to shutdown WiFi and working only with BLE mode ?

* If it possible what the power consumption in this mode ?

Thanks,

Zvika

Hello Zvika,

1. Yes it is possible to switch between BLE and WiFi operations for CYW4343W. Please check /43xxx_Wi-Fi/doc/WICED-BLE-WiFi-Introducer.pdf, it will be helpful.

Also, there would be overlapping of the spectrums for the radio and you have to enable coexistence to avoid interference. Note that default implementation for the CYW4343W chip is TDM type coexistence. Please check: Overview of SECI

2. You can see Section 18. System Power Consumption in CYW4343W datasheet: https://www.cypress.com/file/298081/download

FYI: CYW4343W - Power save
