i set up an coap/iot environment and but i was getting error while compiling code for adc i followed steps from this post devzone.nordicsemi.com/.../ here is the problem
Hi all,
I've developed a broadband vibration energy harvester that is able to pick up uW of energy from just a couple Hz all the way to 150Hz. I'm currently looking for...
We use SDK12.10 Main.c (d:\nordic\5142xx\software\org-sdk12.1\nrf5_sdk_12.1.0_0d23e2a\examples\ble_central_and_peripheral\experimental\ble_app_hrs_rscs_relay.
My question...
Solved: Well, turns out delay and SCK doesnt work well together haha. I imagined the sck signal to be a background thread of some sort. I was wrong.
Hi guys,
at the...
Hi
Im looking for a developer in Denmark to discuss ble technology with. Im trying to get better to understand the technology, because i have some ideas involving beacons...
This system does not work if I enable the third Pipe (Pipe2) .
The system is working without any problem as one RX and two TX (Pipe0 and Pipe1).
The problem on enabling...
Hello,
i have read if not all posts about writing to FLASH while using BLE. But could not find the desirable method.
What i would like to do is to write to flash from...
Hi,
I am doing a BLE based project using NRF51822. I am asked to build a 2 layer board.
According to the reference schematic BALF-NRF01D3 has been used with WLCSP package...
Hi,
I'm close to finishing the implementation of a system with a recording device with nrf51822, working with 6 sensors with nrf24L01.
The recorder is in receiving mode...
I'm looking for an approach to RF coexistence between an nRF51822 bluetooth SOC and a WiFi module such as the WL1801. Does anyone have any experience or recommendations for...
Hi guys,
I tried to flash the pca10001\blinky_example onto a nRF51822 with nRFgo Studio.
Flashing the s110 worked fine. But when I try to flash the hex from the example...
Hello All,
I'm thinking a small plastic case for a portable device.
It is possible to place pcb board (with pcb antenna) above the battery (Li-Po) or can interfere with...
I want to log basic intermittent events and push them to a previously associated mobile device when one is nearby. The mobile device can then forward the events up to a server...
I'd like to know what is the minimum and maximum frequency I can generate on a GPIO with a 50% duty cycle (+/-10% at the worst case). Which resources should I use for that...
In my case active CE signal defines byte boundaries - for each byte individually.
From what I see, DMA seems to stop on rising edge of CS regardless what is declared in...
Hello everyone,
I'm using nRF51822 development kit to do BLE network experiment.
The boards I use are PCA10005 with omnidirectional antenna, and PCA10004 with PCB antenna...
I'm looking at the UICR hardware peripheral example , and trying to figure out the utility in writing to the UICR registers.
Why would I want to modify the compiled hex...
Very new, so please forgive the questions, but...
I have an nrf8001 that I've powered up. After initial power up, I'm able to read the DeviceStartedEvent but the response...
I'm looking to integrate a digital (PDM/I2S) MEMS microphone into my nRF51822-based design. I'd like some pointers to reference designs or other information -- the ones that...
Hi,
I would to know why when the DC/DC is enabled the current is very high (57mA) during RF sending.
Why at the end of RF sending the current is higher than...
I am modifying the bootloader. I am not using DFU or any of that, but rather copying a FW image over from external flash through SPI. The area of my code that gives me problems...
