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...
Hello,
I am trying to understand a bit better BLE throughtput in order to use it for my application, having read this Nordic Blog , this post and ATT_MTU Throughput Example...
Hi!
I have adapted the heart rate example to have just one service and one characteristic. Initializing works fine and I can read the initial value of 0x00 using my cell...
Hi all,
i have a question about the communication client and server.
I'm using for my project a nrf52 and softdevice s132 v2.0.0, reading the datasheet i can understood...
Hello
we have a projekt with periperal "ble-app-blinky" und central "ble_app_blinky_c".
how to do:
when the "peripheral" battery is below 2.3V
then the led 4 on "central...
I'm trying to regularly change some advertising parameters ( ble_gap_adv_params_t.type ). The only way i can see to do so, is by stopping and starting advertising.
However...
I made a pulse oximeter product with nrf51822AC(base on SDK5.2.0 & S110 6.0.0), and implemented SIG GATT-based profile（PLXP+PLXS). Now we want to do BQB RF PHY testing to...
I have an example combining BLE, UART and SPI in which I use RTT to watch the startup process.
The SoC is nRF52 (BLE Nano2); building with armgcc.
This works ok when JLink...
Hi,
I need to send large data(about 200KB) from android phone to my custom board.
Connected like this :
Android Phone ->(BLE) -> nRF51822 ->(UART) -> Custom board...
Hey everyone,
I'm new to the Nordic/Thingy/Embedded world and was hoping I could get some hand holding to achieve a simple change.
I would like to change the Thingy...
Hi All,
I am working printer project where i will be using two boards , one is nrf51 dongle which acts as client(sends/advertise the data) and another is nrf51422 soc on...
Hello community,
I did a central device which is connecting with 8 slaves and this slaves are sending every time 8 bytes when they are connected. My set up is the following...
I'm trying to create a program that takes a stream of UART data at 115k baud streaming in and sends it over BLE as fast as possible. So far, I've
(1)Verified/ made some...
Dear Nordics,
If I add ble_nus service to buttonless_dfu example , it will reset after ble_dfu_init(). If I set
*p_ble_enable_params->common_enable_params.vs_uuid_count...
I am working on S140 on nRF25840. I am using the ble_app_beacon sample.
I want to set the advertising interval smaller than 100ms while using non-connectable mode. But the...
I am developing a product where I need to read a signal from an SPI ADC and send remotely to a receiver. This will be powered of a coin cell.
I see that the NRF51422 is low...
