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...
As indicated in the PS, System On Mode idle draws only 2.6 uA.
Does this mean that if I install and active a timer interrupt, where the interrupt routine places the system...
Hi,
I am new to ARM development. We are thinking of ordering mkit for evaluating and developing a custom BLE service(profile) which sends data to BLE client (probably a...
Hello Everybody!
I have been working with BLE security and I have an issue with OOB setup.
I'm setting my nRF with the following:
m_sec_params.timeout = 30;
m_sec_params...

Yo!
I'm very concerned by what I hear about Bluetooth Low Energy security. According to this guy , who presented a paper on the subject at a USENIX conference last year...
Any experiences about analog sensor LM35DZ? I used this example: main.c
The LM35 data sheet says it will operate from +4V to 30 V supply. I'm use supply only Vcc pretty...
Hi all,
this is not a question per se but rather a warning to those who are attempting to debug Flash related operations with the SEGGER J-Link GDB Server (v4.84a for Linux...
I'm using API 2.1.3 and I'm having problems with SendData blocking forever at the end of a process. I placed access mutexes around each method call to the library, as well...
Dear Nordic Developer Zone,
I have modified the ble_conn_params.c file in order to be able to negotiate new connections speeds between IOS app and Nordic nRF51822 chip...
Hi,
Regarding the bond_info_store() routine, I am having issues where after several calls to this function (client pairing forget/reconnect), my p_bond gets corrupted. This...
Hi, I am developing a BLE application using SPI and TWI. (Using nRF51822)
This discussion is about my survey in development zone for future develop the TWI part.
I want...
I'm calling ble_bondmngr_bonded_centrals_store in response to BLE_GAP_EVT_DISCONNECTED as is the case in plenty of sample code, but when ble_bondmngr_bonded_centrals_store...
Hi Guys,
I have managed to get the BLE DFU demo service working fine (dual bank) on nRF51822 EK. I use a Linux Python program ( bitbucket.org/.../nrf51_dfu_linux) (with...
what is the detection speed, when the beacon
enters into a wall unit area? With their 868 beacon they can
detect in 0,2 seconds. Is the nRF51x22 in sleep mode and does it...
