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...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
Hi all,
I programed hex file (blinky example) to nRF51DK via nRFgo Studio, and the board could work fine (keep blinky).
However, the nRF51DK will work FAIL (LEDs are not...
Hi,
I need to monitor voltage very frequently, have access to the latest value and also to have interrupt on low limit.
But I do not want to have interrupt on EVT_DONE,...
Does anybody knows exact number of the "4 SIG fixed group addresses"?
Is it 0x00? or other?
In the SIG document, there is below chapter.
Group Addresses
A Group...
Hello Sir,
I have developed a product on nRF52832 DK kit and using S132 soft device. I want to flash this same hex file into SparkFun nRF52832 using nRF52832 DK. But i...
I'd like to use nrfjprog to read contents of QSPI external memory. (I'm using an nRF52840-QIAA on a custom PCB, based on the PDK.)
Using application firmware I am able...
Hello
i am using nrf52840 dk with sdk 13.0r3 software.
on first board, using example ble_app_hrs_rscs_relay example.
on second board, using example ble_app_hrs_peripheral...
Hi,
On my single I2C Bus, I have interfaced 4 I2C slave devices.. Now my voltage level of this bus behaves randomly. sometimes It shows 3.3V, but most of the times It stays...
Hi all,
We are currently under FCC certification testing for our custom BLE module based on nRF51822 but failed with the average power exceeding the limit. Nordic Semiconductor...
I'm following the tutorial Development with GCC and Eclipse, but have problem when use GCC to compile project that use PWM library.
I found that when compile the code with...
Hello,
I am getting data from UART and extract NRF BLE packet.
I check the CRC Flag and its OK. But sometimes the UART has some error and I have to check the 3 CRC bytes...
Hi all
I have issues with E-INK display for signals I need 100ns and 500ns delays
but in nrf delay is only nrf_delay_us()
What is easiest way to get nano delays with...
Hi,
I've been working on a way to detect and prevent replay attacks when beacons are used for sensor data. This is mostly used for home automation sensors, where I have BLE...
