Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...

Hello, I'm using the nrf52840 SoC, and nrf52840.h appears to be a more "localized" and "specialized" version of nrf52.h for nrf52840. So quite reasonably I should use nrf52840...
Hello, my harddrive went awry and some part of it were damaged (I assume it was file table because a lot of files are affected simultaneously).
So for the past few months...
In s130v2 SDK12.3.0, ble_uart_c, I have set BLE_DB_DISCOVERY_MAX_SRV to 12. Also memory linker is: IROM1: 0x1B000 size: 0x25000. IRAM1: 0x20001EB0 size: 0xBFC0. I use nrf51822xxaa...
Hi,
I have an application where first nrf51822 would act as central, a second nrf51822 would act as peripheral, a third nrf51822 would act as a peripheral. I found that a...
I have the opportunity to select the voltage of the power supply feeding an nRF52. There no other chips in the system, thus there are no other constraints on the voltage....
I want to sign a block of data from my nrf51822. I though the cryptographic library would serve my purpose. But I am not quite able to get my code working. I tried searching...

Hi,
I have an application, where I need to send beacons and listen to beacons. Is it possible to do both in the same code base, without tearing down the softdevice and re...
Hi,
I would like first nRF51822(device 1) to use Gazelle library to talk with another nRF51822(device 2) and the same first nRF51822 to use Bluetooth to connect to another...
Hello,
i'm currently looking into ble-bcast-mesh with the goal to transfer a large amount of data (up to 1kB) from one node to another. ble-bast-mesh is working (as far...
Using GCC 4.8.4, it seems to me, that the nrf52_common.ld shiped with the sdk version 12.2 contains a bug:
If an image is defined where the .text data fits into the flash...
