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.
When...
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...
We used sd_ble_tx_buffer_count_get() to get maximum tx message can be sent in nrf51. However, this api is removed from nrf52840.
Is it equal to the setting of NRF_SDH_BLE_GAP_EVENT_LENGTH...
I am using NRF52840 and SDK1600. Currently, my program uses 50kB RAM memory according to Segger Embedded Studio. NRF52840 has 250kB RAM memory, so there is plenty of space...
Hi,
We are building a prototype based on the asset tracker demo application. We had interfaced different sensors on different peripherals (2 on SPI and 2 on I2C). However...
I have applied the errata 171 workaround to a zephyr code base with an MX25 chip and set the speed to 96MHz - when I run the application (engineering D silicon) with a scope...
Hi
I have used ble_beacon example to configure DK board as beacon here i wanted to pass custom data inside the code and print those array code on output debug console to...
I have an embedded Linux platform which uses an nRF9160 connected via UART. The nRF9160 has been loaded with the serial LTE modem firmware, version 1.3.1.
I've been experimenting...
Hi!
I'm developing the NRF9160 target from a raspberry Pi. The problem is that I need occasionally to perform modem firmware upgrade, and I can't figure out how to do it...
Hi. I am currently using an nRF52840 DK board and SDK 17.0.2.
I have add a custom characteristic in the heart rate service sample code.
The characteristic is shown on...
Hi Nordic,
I am using your official board nrf52840 to develop my application based on the ble_app_uart_peripheral example. BLE communication and the spi interfaced sensor...
Hi, I'm working with a nordic thingy:52 and SDK thingylib on Android.
The issue I'm facing is that the real sampling frequency, compared to the one indicated by the SDK...
Hello,
I try to use the ASSET_TRACKER application with NB-IoT/ Vodafone in Netherland. Vodafone uses UDP/IP datagrams protocol. is it possible to modify the asset-tracker...
So, we are using NRF52811 with external 32MHz xtal and also exeternal RTC crystal.
Every now and then we are unable to pass tests of the programmed firmware because the...
Dear Sir/Madam,
I have already developed an RF communication device with an NRF24L01+ device. And I want to migrate to nRF52833-QIAA-R. For that, I have the below questions...
I'm using RTC to wakeup every 500ms, I have Watchdog enabled but after a while (about half.. or an hour...) it will not wakeup anymore and watchdog will not reset.
I measured...
