Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
1 sensor per nRF51288.
Sensor supports either 400kHz I2C (10k pull up recommended) or SPI (2MHz typ, Max 20 MHz)
From the nRF51288 Product Specification:
Run current...
I want to use the s130 softdevice because we need the broadcaster/observer mode at the same time. I bought the nRF51 Dongle and the beacon Device.I use the Keil IDE, debugging...
From the question "Advertising on a single channel", the new S110 supports advertising on one single channel. What I want to know is if S120 supports listening on one single...
Hi,
Thank you for looking into this issue.
The target BLE module we are using is a custom board (Rigado BMD200) based on nRF51822 s110 chip. We have tried a few example...
Hi,
I am following the tutorial using Raspberry Pi Kernel version 3.18, but after the step 7, the raspberry gets frozen with the colorful image in the beginning of the boot...
Hello,
we want to establish a UART communication between the Dynastream N548M8CB Module and a TI Mikrocontroller. I have tested the UART loopback example with the pca10028...
In the data sheet of SHT21 is this the formula to calculate the temperature:
T = -46.85 + 175.72 * temp_data / 2^16
temp_data has the value 26'464.
The result should...
Hi,
I'm trying to define a new service, and on the GAP settings, I would like to advertise my service, but I get an error message: advertisement packet too long.
What...
I have a temperature/humidity sensor from Sensirion. The Type is SHT21x. The sensor has I2C so it should be able to tranfer the data from the sensor to the Nordic chip over...
Hi,
I am attempting to get the ble_app_beacon example working with the s130 softdevice instead of the s110. I am using armgcc and the v8 sdk softdevice headers on a pca10031...
Hello, I have inherited a project from a departed employee. I have a requirement (based on a stated desire from her to my project manager) to "bring the SDK and/or SoftDevice...
Hi,
I am using the nRF24L01+ evaluation kit in a project. Through the EV KIT software I am able to configure the nRF module in receiver mode. I can even see LED 2 light...
Hello,
I am trying to modify the ble_app_uart example from the S110 to the s310 softdevice. I am using the project from nRF51_SDK_8.0.0_5fc2c3a.
I modified the Paths...
Hi,
We are planning to design a custom based on nrf51822 with 1.8v power supply. we just want to know is there any restriction towards accessing peripherals on chip like...
I don't understand how the numbers in the nrf_pwm_init are calculated. Specifically these:
case PWM_MODE_LED_100: // 0-100 resolution, 321Hz PWM frequency, 32kHz timer...
