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...
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'm trying to use sine function such as: S = sin(0.8)
But variable S come to zero after this code. Go to Debug mode and add a break point to view the change of variable...
Hi,
can we do the mathematical operations (like math.sqrt ) using nRF51822 ? Since, our project requires many simple mathematical operations, we need to decide whether...
Hi,
During the initialization of the SIM I have this message:
There was an error submitting your user information. This SIM cannot be activated. I am from Israel. What...
Hi All,
I have the strange issue with scanning. I have the project losely based on examples where I created peripheral adevrtising with 1s interval. This sends the custom...
Hi there, I'm using nrfutil ( nrfutil version 6.0.1 ) to dfu via ble (dongle),
Mac (10.15.2), windows (10), linux (raspbian) have been tried out to update the firmware none...
I am using the '840 to construct a small network using the ESB stack. In this design, a master (dongle) transmits to each slave and receives an ACK w/payload response. The...
I changed the way to get the upgrade program in the bootloader program and wrote a function to write the accepted bin file to the bank0 area. However, I found that it took...
Hi,
I am using BMD300 rigado board having nrf52. In my application i am tracking the ADXL362 accelerometer's motion.For this, I am combining SPI, UART(for displaying data...
Good evening,
after a very long research I couldn't find any answer.
Is (and if, how) it possible to connect an Arduino (or ESP32) via SPI, I2C etc. with the nrf52840...
Hi,Nordic Team
I tried to set 0,1,2 modes respectively in GNSS option, and the test current is as the attachment .

Hi,
I am using nRF52832 with s112 BLE stack and SDK v16.0. I am wondering what is the most proper way for the "idle_state_handle()" method in the main loop.
Currently...
Hello,
I need to have connection status at the application level (IOS).
I'm working with the example "light switch server proxy" where the heartbeat profile is working...
Hello, I modified the instance in usbd_hid_generic to simulate it as keyboard. I checked the code of NRF52840 on github about the keyboard. It USES the function app_usbd_hid_generic_in_report_set...
