Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
i made this project to try to create RSC service on arduino
developer.bluetooth.org/.../runningspeedandcadence.zip
unfortunately the server starts but i'm not able to...
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.
typedef...
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...
Hi All,
I have a basic question about advertsing data, more precisely about device's address.
I try to disable in my advertising data, the address field but it doesn't...
Hi I followed the Nordic UART example code to read and write characteristics to a Nordic S110 nRf51822 device.
My code is the same as in writeRxcharacteristic but when...
