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.

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...
Is it acceptable if I stop an app timer for dozens of times when the app timer is actually stopped.
Will the memory leak if I operates in these scenario.Does it affect whether...
I am considering using the nRF51822 for an upcoming project for a client. It is a simple BLE peripheral, so I would use the S110 SoftDevice for the stack. I am looking at...
I use BLE mesh github.com/.../nRF51-ble-bcast-mesh
but when I use the master control to write values to update the values of services, the following error occurs: "global...
Hi,
I have implemented the support for 'long write' as in
github.com/.../ble_app_hrs---LongWrite
which works from the MCP... except that on BLE_GATTS_EVT_WRITE, it seems...
I have bought nrf go starter kit with pca10005 board( nrf51822 ic). I want to program the nrf51822 using these tools.The guide that I got from the nordic website not explaining...
If the device is paired (but not bonded) using "Just Works", sd_softdevice_disable() causes the application to hang/crash (nothing happens until reset by watchdog timer)....
I want to generate 2 fast PWM waves with 25% duty cycles from nRF51822. They have same frequency of 4MHz but there is half a cycle delay between them. I checked the nrf_pwm...
Hi,
I am trying to get the NRF8001 rev. C chip working with a Tiva Lauchpad (TM4C123GXL) board. I modified the original Arduino SDK for use with Energia. I am using the...
Hello,
i want to write a global unsigned long variable in RAM after programming the device. The Use-Case is to set the clock value to the actual time. So the new unsigned...

Hi. All.
I am in the process of update SDK 9.0 from 5.2.
Meanwhile, SPI couldn't read from external flash's data.
Unusually SPI works well before infinite loop, I tested...
