Hi ,
I am trying to implemenent DFU on nRF52840. Aim is to store new image to slot on QSPI external flash but it seems like nothing is sored on slot 1 as when I upload...
I'm trying to set up TIMER0 to interrupt the timeslot 500us before its end.
It doesn't seem like the NRF_RADIO_CALLBACK_SIGNAL_TYPE_TIMER0 signal is happening, I've put a...
When I try to enable SD having earlier initialized Gazell (SD resources variant) sd_ble_enable() returns 2 (SOFTDEVICE_NOT_ENABLED). If I remove the Gazell initializaton it...
I am trying to work with a custom 3rd party BT 4.0 peripheral device which uses an nRF8001 to transmit data as temperature values in the Bluetooth Health Thermometer service...
Hi,
Slight problem here with bootloader updates : right after download, I copy from SWAP (0x16000) to normal location (0x38000 in my case).

I am wondering how to precisely measure my power consumption. Till now, I have been using INA216 on PCA10004 board + labView for acquisition, but it is not precise enough...
I was working my way through the app note nAN-36, where it says you should have a seperate source and header file for each service. However in many of the newer SDK examples...
New to embedded world. Trying to interface MPU6050 w/ nRF51 DK via TWI. I have included the external MPU6050 drivers and everything compiles in Keil (except for last few lines...
I will be building PCBs with an nRF51822 module. I was reading in another question that perhaps the best way to program the nRF51822 on multiple PCBs is to use the SEGGER...
The nRF51822 softdevice is generating the following disconnection event:
11:20:09.363365 : BLE_GAP_EVT_DISCONNECTED c=x05dd
11:20:09.365011 : reason = x002a
11:20:09...
The Health Device Profile is continua compliant. Are BLE health related profiles like Heart rate profile, thermometer profile continua compliant as well? Do these profiles...
Hello, I was wondering what the proper process is to set the measured RSSI values at 1 meter is. RSSI at 1 meter is a part of the iBeacon standard, and is also useful for...
I am PHD student in china and doing research about gait retraining. I am designing wearable sensor that monitoring gait and giving vibration feedback to retrain the gait and...
I've implemented my DFU app on Android(4.3). During the test, I found a strange problem, that the performance of writing image data into swap area is very very slow. My Softdevice...
