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 guys!
We are workng with nRF52840 SoC and SDK v17.0.2.
Custom BLE Services and Characteristics are needed to implement in our device. Before starting that implementation...
Hi,
In our design, nRF9160 is powered by a LiPo battery, making VDD = 4.2V in a "fully charged" case, and VDD=5V in a "lipo is charging" case.
We would like to be able...
In trying to use a private key file to sign the application image I'm running into an issue with the PEM file. I created a PEM file using the following command:

Hey there,
I am new to the community and I would like to looking for more than one cell. As I readed in another thread, it was possible with %NBRGRSRP a few month ago. ...
I was looking through documentation and I noticed that in OPS v0.7.1 the cold start was stated to be -144dBm. In PS v1.1 it calls out -142dBm. Can you explain why they are...
Hi!
I have BMD-350 -A-R and I want to program this by using SWD pins (SWCLK, SWDIO, GND Detect, and VTG) of Nrf52Dk . I make all the connections properly but for some reason...
Hi,
for evaluating purposes I'm trying to send quite big amount of data (100 kB) via socket interface. Sending proceeds fine until approximately 60 kB is transmitted. After...
Hi,
when powering up the nRF52840 PDK its interface MCU LED is blinking fast and the board is not recognized. I've tried to update its firmware by putting the board in bootloader...
On some android phones we have observed that if we try to scan using nRFToolbox for nRF51/ nRF52 controller advertising with UART they do not show up in the scan list. But...
Hello,
I am developing a wireless sensing device using the nRF24L01+ module and I'm planning to use a u.FL connector in my design. I can't seem to find any manufacturer...
Hello,
I am trying to test BLE with SAADC, UART function.
I am complete the ADC test and UART part.
So now, I want to SAADC with BLE and BLE with UART.
The whole connection...
Hi all,
I tried to follow this tutorial to be able to use GDB as debugger but failed right in the beginning because JLinkGDBServer could not connect. Here's the log I get...
