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...
We have an odd one here. We have a single nRF51822 (QFAC) board that is acting odd. None of the other boards exhibits this behavior. They program perfectly. 3.3v supply is...
I have been having two issues (possibly related) with the RX pin of the nRF52 DK (PCA10036) using the ble_app_uart example. I have been trying to characterize the problem...
Hi all,
In my application, I take mac address of chip and make major, minor value (device 's ID) and I need mac address is a constant value. As I know, mac address is a...
because license is so expensive, I'm converting my project to OSX GNU
I'm solving problems step by step..
and there is error that I couldn't understand.
Anyone can...
Is there any way to control BLE shield 2.1 from PC rather than android / iOS app.
Also if i pass any message to BT dongle how to check the received messages.
And in...

I see a debouncing filter in the block diagram of NRF52 preview DK. Isnt debouncing implemented in software? So why need a HW debouncing...
Hi all,
I have two kinds of NRF24LE1 devices(A and B), and I want to realize that one device_A can communicate with 10 device_Bs at the same time. To explain it in detail...
I would like to use 3 PWM for controling RGBs. I use a softdevice because I want to control the pwm trough the MCP. But for now I just want to get it work to initialize these...
whether linux and bluez implemnted the simultaneous master and slave connections......?
or is it part of link layer only..?
does this feature need kernel support or not...
In the NRF51822 reference manual, the debug interface mode initiation routine is described as follow:
150 clock cycles with SWDIO=1.
I have already verified that a standard...
Hi,
I am wondering about the Cumulative crank revs for service 0x1816 & 0x1818
Cycling Cadence and Speed, Cycling Power Services
I dont understand why the crank revs...
Hi Guys,
I have a MCU RTOS project. in Hardware board, builtin Nodic BLE chip over UART,RTOS BLE stack works fine.
We also have a MCU RTOS Emulator based on Qemu,we...
Ok, so I've been trying to get to the bottom of a problem for a few days now where suddenly the app_timer is acting like it's on crack and running super fast, i.e. triggering...
