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.

Hello,
I am using PCA10028 and sdk 12.2.0. Now I have interfaced temperature sensor and I am storing 4000 readings from sample to flash. Once all the 4000 samples are stored...
When I enable DLE with a max MTU size of 247 (NRF_BLE_MAX_MTU_SIZE = 247) and PDU payload size of 251 (opt.gap_opt.ext_len.rxtx_max_pdu_payload_size = 251) and a max characteristic...
log.txt I have programmed my nRF smart beacon with example peripheral code with DK52. My beacon now flashes red. I am using the nordic sniffer to sniff ble packets in wireshark...
Hi,
I will be using ble_uart application code in my nRF52 Evaluation board. With nRF52 EVK I will be connecting external module over UART communication. I want to detect...
i am having trouble with pwm module 2. only two of the channels are working but not the third nor the fourth.
i tried pwm module 1 but im having the same problem there. i...
I'm currently working on an esb project using two nrf52832 chips wherein PTX regularly sends packets to PRX as a kind of heartbeat monitor. I can't seem to find what happens...
Hi,
I get the ble_app_att_mtu_throughput -example working with the coded PHY between two nRF52840 boards. Very nice, although I did not yet get the coded PHY advertising...
Looking at the ble_nus service, I see that the SoftDevice allows notifications to be more than 20 bytes long:
