Or is there any LCD you could suggest that doesn't need that much code? Simple numeric 2rows would be enough. Want to use it with the nRF51-DK to display some measured valued...
I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hello. Can I get a literature to the nRF51 series?
I need a full abstraction of the nRF51, like a book or other information, it's structure schematic of build-in modules...
hts, HTC phone, nrf tools HTM, nrf51822,
every time when it's power up :
the once connect: error code 0x7A cann't read characteristic and 0x14 state change.

Our company needs wireless temperature sensors (can be externally powered or battery operated) and transceiver with 4 channel analog outputs. It has to be finished product...
Hi Folks, I am playing with uart ble example described in this link ( devzone.nordicsemi.com/tutori...).
I would like to make BLE uses a unique AA (Access Address) rather...
Hi,
for my sound application, I want to get the amplitude, or dB, of the PDM samples.
Are there any existing function implemented? If not, how can I code it on my own...
Hi, I just started using the nRF52 dev. kit. I am trying to familiarize with the BLE examples.
I have downloaded the nRF Connect...and I can detect the device.
The SDK...
Hi,
I added one more timer. As soon as the timer expires and it runs the event handler, and then advertising stops, and the firmware crashes.
Could someone please tell...
I've recently discovered the power consumption issue with FreeRTOS and SDK12.3:
devzone.nordicsemi.com/.../
So, I am now using SDK12.3 with SDK13.1 FreeRTOS files.

I am using Nordic SDK to program an nRF51822 chip. I want to optimize power consumption as much as possible so I am looking at using the -march gcc flag. The problem is I...
I am using the ble_peripheral template that comes in Nordic SDK 8.1. I setup uart logging and also debugging with the following lines of code:
void assert_nrf_callback...
Hi, We are trying to connect a LED to one of the GPIO of nRF52840, we would like to know how to connect it. Connect it such that the nRF52 GPIO sink current or source current...
Hey, I am using WT51822-S4AT module and want the nrf51822 to connect to phone. I don't have nrf51-dk. I am using stm32f0-discovery kit. Can it be done using that kit? I searched...
Seems battery reads are not consistent in thngy52 2.1.0 software.
Observed a ~4% difference in the consequent battery reads. This difference is high (upto ~40%) if the thingy...
In the recent past, I used a SoC in which GPIOs could be configured as "open drain", that is in which there is an internal transistor where the SOURCE is grounded, the DRAIN...
