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,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
Hi,
I am able to change the MAC address of the beacon using the call sd_ble_gap_address_set(BLE_GAP_ADDR_CYCLE_MODE_NONE, &gap_addr), where gap_addr is of type BLE_GAP_ADDR_TYPE_RANDOM_STATIC...
Hi, I am newbie at this field.
I have tried to configure network for communication between device nodes.
What i want to do is each device node has unique data( <30bytes...
Hi,
Is it possible to control the ouputs without connecting?
I mean something like this:
I have a nRF51DK. And I would like to detect if there are bluetooth devices...
I'm trying to get some sound out of a piezo buzzer using the PWM library here:

Hi all,
I am looking for some help on where to identify a problem that cropped up recently. I'm relatively new to the softdevice concept, though it seems straightforward...
Hey everyone,
I'm developing an application using the PCA10001 board. After a while my app crashes. I think this is due to un-freed memory regions. When writing similar...
Hi every one,
I work on application that read continuous analog signal with 500 sample/second and send it from nRF51822 board (1) to nRF51822 board (2) and read this value...
The BT SIG has adopted the "Indoor Positioning Service" and in there it says ...
"When a characteristic value is written, the Server may check the validity of the value...
Hi,
I need to send an audio signal through BLE connection of nRF51822 module, this signal need to quantized and sampled at rate of minimum 8000 sample/second by ADC, i...
I would like a working example of a simple application that uses soft_device (either S110 or S120) plus UART debugging.
I have read many posts in this forum about this topic...
Hi folks,
do you supply a BT Test-SW to set a module with your NRF51822 in different test modes like continuous FH etc. or to change the device to low, mid, high channel...
Hi,
I want to establish a peer-to-peer communication network between 2 nRF51422, such that both the nRF51422 can Transmit as well as Receive data. Is it possible to achieve...
hi,
as we know, the device need to being linked in 1.28s if Advertising types is BLE_GAP_ADV_TYPE_ADV_DIRECT_IND ,but my host can't link device in 1.28s,so i want to link...
