I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
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...
Hi
I thought: let us quickly migrate to the latest SDK.
But that seems to be harder than anticipated.
I run into a number issues when compiling with the new code:
