We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
I am interested in writing a BLE central that reads data from multiple BLE Nordic sensors. The BLE central will be running on Embedded Linux which uses the BlueZ stack.

Hi,
I'm trying to get S110 softdevice (v8.0.0) working with RIOT. I had some issues (I couldn't initialize TIMER1 or TIMER2 until softdevice is setup & enabled) but I think...
Hello together,
we are running the DTM in different modes to check the module (nrf52832, sdk 5 version 11). The carrier test gives us a current consumption that meets the...
Hi
I try to program Insight ISP 130301 with a hex file, which works on nrf51 PCA10028. Unfortunately, it doesn't work. I try to loop for each pins and set it's state, and...
I'm trying cominicar me through Termite between the application plate (nRF51-Dk kit) and a device that supports BLE, but the connection between PC and the kit application...
I was working with IAR and SDK10.0 before. For some reason I have to transfer my project to Keil and SDK9.0. My program worked well for the old settings. While keeps got NRF_ERROR_SOC_NVIC_INTERRUPT_NOT_AVAILABLE...
Hi again, I posted earlier in another post that my writeCharacteristic is responding with status 6.
Details:
Android version: 5.1
Nordic device: nRf51822 S110
I have...
Hi
I want to use nrf52 LATCH register.
I can see the correct bit set in the register, but I am unable to clear this bit.
I have tried NRF_P0->LATCH =0xFFFFFFFF; for my...
Hello
I am doing a PCB design using nRF51422-QFAC chip. I did based on nRF51-DK but now I would like to change for a SMD antenna (2450AT18A100 from Johanson Tech.) instead...
Hi ,
I am working on one application in which i need to stream the ADC values over BLE to the mobile App. This should happen at very high rate i.e. 1000 samples per seconds...
Hello,
I'm trying to do something like ibeacon where data is pushed to any device listening, but I want to update the advertising data from raspberry pi 3 since it supports...
Hello,
I am working on an application where the nRF51 acts as both central and peripheral. The device is in permanent connection as peripheral while scanning for other devices...
Hi
can ESB be considered RealTime transfer as soon as it has it's timeslot?
Outline of use-case:
Device advertises existenace on BLE
If there is data waiting...
I am trying to implement a REQ line protocol over GPIO to signal to the Master when it is ok to receive data. Basically, I want to pull the REQ line high when the nrf51 has...
Hello,
Ble spec says that "new alert" characteristic - field: "category ID" can have 1 or 2 bytes.
here
But it seems in your struct you let it have only 1B.

Hi,
I have ordered a PCB using the reference schematic for NRF51422 user guide.
I wanted to know whether the schematic has the required antenna design or I need to add...
