After I get a Disconnected() event, I want to start scanning again, therefore try to call StartDeviceDiscovery() again.
IsDeviceDiscoveryOngoing was checked before.
The...
Hi, I wanted to ask a question regarding sending data.
I currently have external memory that will send out serial data (SPI) to the nordic microcontroller. I have saved...
Recently, I try to programme nRF51822 DK communicating with nRF2401e1 DK,unfortunately，which does not success. With setting radio configuration: TXPower,frequency channel...
Hi,
I have shifted from Arduino to nrf. Arduino is straight forward and with very less dev time. I understand this is way more powerful and next level platform, but does...
I am trying some scanning with a parameter setting, code below. The scan start, I am guessing by the call to nrf_ble_scan_start, generates the error sd_ble_gap_scan_start...
Recently got my Nordic Thingy:52 which is based of nRF52832. I wanted to test sending the data to cloud, so I just followed the IFTTT tutorial on the Android Nordic app. I...
For a design consulting client, they have a startup problem and need to know the approximate leakage current when a GPIO is in "DISCONNECTED" state.
I know the NFC pins...

so, after getting it to compile, now i can no longer write to flash memory and i don't knwo why i am getting this error now. now sure if it is a result of nrf_dfu_flash and...
hi.....
i am interested in Mesh ,actually i want to understand the flow of mesh program (eg light switch example )how does it work,how it transferring from client to server...
Hi all,
In order to lower the power consumption of my device I have been experimenting with WFE. When using WFE I see that the interrupt latency is increased from ~4µs to...

I have 40 kb of data i need to send, and what i thought was using notification by creating a timer, which will be started as soon as device gets connected, in...
I am trying to interface with a I²C OLED display using Zephyr’s SSD1306 driver. The driver uses i2c_burst_write, which itself requires that i2c_transfer support gather writes;...
This is on SDK 15 : Not all services are reported when doing service discovery on more than one connection at a time.
Basically, ' ble_db_discovery .c' uses ' m_pending_usr_evt_index...
Hello, I am using the nRF51422 Development kit with SDK11. I am using the proximity application for the battery level service. I would like to strictly advertise to a single...
Hi,
I have an application where I have for example 5 BLE transmitting devices . Each device has one push button and each device is assigned to a number 1-5. I also have...
