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...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...

I am trying to interface I2C EEPROM (AT24C512) with nrf52840 and I am directly writing to and reading from the registers mentioned in the datasheet. I am seeing the i2c waveforms...
Hello -
We are also bumping into the problem described here , where it is not possible to initialize LESC when BLE is initialized from a FreeRTOS task. The nrf_stack_info_overflowed...

external board with 51822 and mems
I connect my external board with nRF52DK as this (left is board, right is nRF52DK):
SWCLK -> SWDCLK
SWDIO -> SWDIO
VCC...
Hi,
I got some troubles on the communication distance between the two units which one acts as central and one acts as peripheral, I tried to adjust the BLE parameters the...
Dear Sir,
I have enabled my project for SPIM+EasyDMA.
I am configuring the SPIM transfer nrf_drv_spi_xfer with additional flags like,

nRF51822 QFAA
At first I set up the RAM size to 0x1F80, it works fine. However, after I try to use RTT to print log, I got the compile error: region RAM overflowed with...
Hi ... how to set the password to secure the connection between the device and application . I don't want to anyone to connect my device , for that i am planning to the set...
I have a nRF52 DK. I'd like to debug my board which has nRF51822 and sensors, and has SWCLK, SWDIO, VCC, GND, RX, TX, VCC, GND. Please provide detail steps on how to wire...
I'm developing a central that discovers services in a peripheral. The services are both custom and standard BLE services. Discovery is working fine, but there is one issue...
Hello,
We are experiencing a rare condition whereby we read in raw Accelerometry data (758 bytes) over the SPI bus, and sometimes (rarely), we'll get a block of repeated...
Hello Everyone, I designed and fabricated a small nRF52 board. The design of this board is based on the Adafruit nRF52 feather. The difference between my designed board and...
Hi,
I'm working on MacOS 10.14.6 and I'm having trouble with the Programmer app in nrf Connect.
I have installed the Jlink driver successfully (v6.60a), but when I select...
Hi, I am trying to add a motion sensor event into my code that utilizes the low power accelerometer on board the thingy91. I wont be in sleep mode but will be in PSM or edrx...
