I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.

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...
Hi,
I am using NCS v2.4.2 and nRF5340DK + nRF21540EK but I can not enable GPIO+SPI mode.
for example, I use nrf/samples/bluetooth/central_and_peripheral_hr application...
I manage to connect to the network and disconnect from it after sending the data, but if I'm in an area without reception, the device tries to connect and after a while, the...
: Chip Not Recognized by J-Link
I need advice from someone familiar with the nRF9160-SICA-B1A-R7.
I purchased an nRF9160-SICA-B1A-R7 chip individually from Digi-Key and...
Dear Sir :
We are now developing on nrf52840, with ncs v2.6.1 and zephyr.
We want to put I2C0 to PM_DEVICE_ACTION_SUSPEND before sys_poweroff().
Our code is below :...
Hello everyone,
I am currently trying to get a ML model running on my nRF52 (preferred nRF52832 but nRF52DK works also for me). Right now I am trying to evaluate if my setup...
We have using nrf5340-nrf7002 in our custom board. SDK version 2.6.1 We understand that the timer will not function in System OFF (deep sleep) mode. However, our project is...
Hi there,
I've encountered a strange PWM behavior and have investigated a bit. When setting load_mode to NRF_PWM_LOAD_WAVE_FORM, creating two sequence, and the latter sequence...
Hello, We want to build our own custom protocol because the features we need are not available from existing protocols like BLE or Zigbee etc. But it is beyond our reach to...
Hi all,
In my application I need to use some of the NET core peripheral from the APP core (since I ran out of peripheral instances in the APP core). According to this page...
I am running into an issue (title), where I am attempting to switch the advertising interval to a slower interval after a set period of advertising in order to save power...
Hello everyone,
I'm trying to test the ble_app_uart example. When I download the code into the 52DK, i can see my device show up as a possible connection, but when i connect...
We have a number of fixtures using nRF52 DK boards to both flash a custom board and to do a DFU operation to that board. We use a SPST switch in the P19 pin 1 lead in the...
Good day
Our custom board contains RS485 implementation. The file schematic for that looks like this:
I have noticed that a driver and sample exists but the driver doesn...
Hello everyone, I'm currently updating my project from SDK v10 with softdevice S110 to SDK v17.1 with softdevice S132 (a huge step). I'm, wondering if what I want my code...
Hi
I am trying to make a SPI connection with a device which doesn't already have a driver build into Zephyr.
Is there some kind of genereic device i can use since i just...
