I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
ble_gatt_db.h and ble_db_discovery.h each contain #defines that are problematic, BLE_GATT_DB_MAX_CHARS and BLE_DB_DISCOVERY_MAX_SRV respectively.
Of course, one can change...
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...
