We use NRF52832 in the remote control of the car。 We measured the average current of power consumption at about 1uA.Every 300ms, the current curve bounces to the transient...
I would like to use the RTC in the nRF52833 as a clock-calendar. The device will normally be powered by the USB Vbus but must have power fail protection to insure the integrity...
Hello,
I would like to create a star network (with no routers) in ZigBee with nRF52 (also with multiprotocol BLE). I examined the relevant SDK (nRF5_SDK_for_Thread_and_Zigbee_v4...
My setup is a custom board with the nRF52832 and a remote BLE client e.g. nRF Connect tool kit on an Android phone.
The application periodically broadcasts a 'beacon' but...
