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...
Hello,
I am using the Thingy:91 PCB and I have disabled the nRF52 by cutting SB4 and soldering SB3. This makes me unable to log through UART. For this reason I implemented...
To the kind attention of Nordic support team,
I need to disable, enable gzll more times. When enabling it, code gets often stuck in my case as in figure: nrf_impala.c 442...
I have achieved Bluetooth connection between 1*ble_central<------>6*ble_peripheral.
But, ble_peripheral sometimes upload data at the same time, then sometimes lose data...
We're successfully using nrf_crypto_aead_crypt() with AES CCM, a 128-bit key, a 64-bit MAC, and the NRF_CRYPTO_ENCRYPT operator to encrypt some data and generate a MAC that...
HI, all,
I am trying to transfer my previous project from nrf51822 to nrf52840, and at very the beginning ,I can not make the UART/UARTE of nrf52840 work.
0, I have programmed...
Hi, everyone,
I am pretty new to nRF52 development. Right now, I have an issue with the SAADC trigger by RTC, which I follow this example . The issue that I have right now...
Hey all,
Here's another question. Many of the examples in the Nordic Connect SDK are rather large. Transferring them with MCUmgr at 115200 BAUD takes sometimes more than...
Hi
I am testing sending and receiving data between nRF51 dongle and peripheral by example of heart-rate-collector.
now I could find characteristics I need(write, read...
Hi all,
My application is as follows:
I have an android app which will send some data to a nRF DK. The data I want to send is in HEX characters between 0x00 to 0xFF. And...
Hello,
For nRF51822 and nRF52832, I'm using GPIOTE, PPI and timers to measure the duration that a pin, which is normally low, goes hi (typically 100-300 milliseconds). I...
The following questions are in regards to the instructions at nRF_Connect_SDK-modifying-a-sample-application .
In the Windows environment, I am transitioning from using...
Dear all,
I recently made a custom PCB using the aQFN73 package of the nRF52840 and, even though I respected the antenna constraints (but in 2 layers) I get no signal whatsoever...
Hi Devzone:
I am using P0.00 as SDA and P0.01 as SCL on nRF52833, And I got waveforms like below when I am doing I2C transactions:
the red waveform is SDA and the green...
