Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
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...
I'm trying to change channel id with no luck while I'm in EVENT_TX state. It seems that if I call sd_ant_channel_id_set while in EVENT_TX broadcast data gets reset to zeros...
I'm working in the ble_app_lbs example, with a PCA10001 eval board, softdevice 110, and Nordic's Master Control Panel.
In the example code, I've changed button 1's functionality...
Hello
for a 4 layer design with the nRF51822, how is it best to choose the layers? In the datasheet of the balun (bal_nrf02D3) there is a hint, I guess it is more or less...
Hi, could you please tell me if my assumptions below correct?
Measuring a (ratiometric to VCC) analog signal and selecting VDD_1_2_PS as the reference selecting AIN_NO_PS...
How many whitelists do nrf51822 support?
I found is can be settting in ble_gap.h
#define BLE_GAP_WHITELIST_ADDR_MAX_COUNT (8)
#define BLE_GAP_WHITELIST_IRK_MAX_COUNT...
I'm working on a project that involves an nRF8001-based device as a Bluetooth Smart slave, in combination with master-side software running on an iPhone.
When the devices...
Hello
I have written some code to write the nrf51822 via SWD. It all works, but I would like to make it faster.
I am currently writing one word at a time. If I read...
Hello dear friends,
I'm trying to bring up a Raytac module for the first time. I was able to program S110 7.1 and I'm using the Beacon example found in the SDK 6.1
But...
Is there a similar way tot get the radio's MAC address when using Gazell only (no BLE)?
In SoftDevice there is a "sd_ble_gap_address_get()" function call.
Hello All,
I'm trying to program a NRF51822 module for the first time. I'm using the Jlink for ARM from IAR which is segger rebranded. It supports JTAG and SWD.
We got...
Hi,
I am trying to obtain a 10khz PWM (50%) on an output using Timer2 (see code below). It is working fine up to around 500Hz (2msec), above that (1kHz) I am getting only...
I would like to develop an application with nRF8001 DevKit. The master emulator of this kit is an USB Dongle and it is originally meant for PC connection. My final goal for...
Hi all,
Problem: Second harmonic with nrf905.
I used nRF905 and exact recommended design&layout in the datasheet. Now, it is said that there are 2. order harmonics ...
