Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
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...
trying to update date for BLE device but getting this error "Error changing notification state: The request is not supported."
Trying to write date: on nRF52 device

We have successfully implemented the Template app on Android. However, the architecture of the multiple services and layers is somewhat opaque. Three questions:
How...
hi ,we have test the example of ble_app_att_mtu_throughput in nrf52840 ,the other side device is an android phone .
nrf52840 would freeze when the phone want to feature request...
Hello! I'm calculating the matching circuit with the antenna for nRF52832, but nowhere can I find the impedance value of the pins of the radio part, can you help me?
Hi,
I'm working with a nrf51822 based hardware which came programmed with some UUIDs and S110V7. Erased it completely, experimented with some non SD code first and finally...
Hello! I have a problem with checking the microcontroller nRF52832. J-Link does not connect to nRF52832, the screenshot of the Segger-commander window is shown below:
...
Bit of an odd question but Im dealing with a rather wonky SPI peripheral and its got me trying to sort some interesting questions due to its strange data protocol. Im using...
We are using the Android nRF toolbox v2.4.0 and have successfully implemented the Template app. The app will reliably connect with our device and functions well. The only...
Hi,
I was wondering if the SPI configuration for the p_config->sck_pin is correct. It appears that the clock is configured as output with input connected. Wouldn't this...
I am searching for long time how to inspect the prints in my code inside Segger , I went over many messages in this forum and nothing comes easy to me with this Segger thing...
Using Segger , only the BLE template is advertising,All other BLE apps such as BLE_UART, will flash the leds very fast but will not show on any Apple device on the Bluetooth...
We have an ISR parsing incoming serial data from the UART. When a valid packet arrives, I'd like to be able to wake the core from whatever low-power state is entered when...
That is probably an old topic, but after doing some research I could figure it out: calling sd_app_evt_wait() on my nRF5832 + nRF5 v11.0.0 SDK + s132 causes my chip to reset...
