Hi,
I'm starting to implement DFU using IAR's ARM workbench. In the example project for ARM that comes with the nrf51_sdk_v5_2_0_39364 SDK there is a file called bootloader_util_arm...
Do I have to use external host MCU for nRF51422? What can the ARM Cortex processor inside SoC 51422 do and cannot do?
I want to create a mesh network with hundreds of ANT...
Hi
I am looking at section 9.1 of the S110 Softdevice Specification v1.3A and the release notes for 7.0.0-2.alpha where I see that an application now starts at 0x15000...
Hi
S110 v7.0.0-2.alpha got released today.
In the release notes it says...
[b]The SoftDevice can now be configured to forward interrupts to one of several applications...
Hi,
I use the nrf51422 chip.I want to know if the ANT establish link between chips,where can I get the matching configuration (like device type、channel ID).I mean is...
Is there a way to recieve more than one write callback for a given characteristic, per radio session? It seems like I can rx 1 time per attribute per radio session and tx...
I've recently discovered the power consumption issue with FreeRTOS and SDK12.3:
devzone.nordicsemi.com/.../
So, I am now using SDK12.3 with SDK13.1 FreeRTOS files.
...
I am using Nordic SDK to program an nRF51822 chip. I want to optimize power consumption as much as possible so I am looking at using the -march gcc flag. The problem is I...
I am using the ble_peripheral template that comes in Nordic SDK 8.1. I setup uart logging and also debugging with the following lines of code:
void assert_nrf_callback...
Hi, We are trying to connect a LED to one of the GPIO of nRF52840, we would like to know how to connect it. Connect it such that the nRF52 GPIO sink current or source current...
Hey, I am using WT51822-S4AT module and want the nrf51822 to connect to phone. I don't have nrf51-dk. I am using stm32f0-discovery kit. Can it be done using that kit? I searched...
Seems battery reads are not consistent in thngy52 2.1.0 software.
Observed a ~4% difference in the consequent battery reads. This difference is high (upto ~40%) if the thingy...
In the recent past, I used a SoC in which GPIOs could be configured as "open drain", that is in which there is an internal transistor where the SOURCE is grounded, the DRAIN...
Hey,
I'm using nRF as a SPI slave with a Raspberry Pi. I'm seeing that even at ~3MHz SPI frequency, my first byte transferred gets corrupted. I have a test setup where...
I am using nrf52 with s132 and armgcc
As I add functionality to the code I get to a stage where it fails. Linker runs OK but the result fails to execute.
The observable...
I am currently working on a BLE beacon project on nRF51822. Using SDK 12.3.0 and s130. The device has to advertise URL, advertising name and output power level. And these...
I am trying to control a current measurement chip (DDC114) that works with a protocol that is close (enough) to SPI. It has 2 channels, s.t. it can be read out and integrating...
I am attempting to run my first bit of code on my Nordic nRF52-DK and every time I have attempted to upload the code to the board, the board disconnects in the middle of the...
