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...
The debugger does not work with the latest GNU toolchain for ARM Cortex-M build. It throws the following error on Eclipse:

GPIOTE Library makes my Board(nRF51422-QFAC) Brick??
I just build my nRF51422 Board, and It's pretty working well before I've used GPIOTE Library.
Before using GPIOTE...
Hi everyone,
I am seeing an issue where the SPI (master) ignores the first byte of RX buff and begins storing the received bytes from RxBuff[1] instead of RxBuff[0]. In...
Does anyone know if there is any documentation of nrf51822's current consumption? Perhaps, something similar to CC254x's Application Note . I'm mostly interested in the current...
Hello,
I would like to build two boards that can send small messages between them, at long distance. For that I would like to use some of your devices (I used 51822 in...
Hi
I have working module which communicates via uart with another module. It works good, unless it is heated to 40C. After that temperature UART communication is not correct...
Hi Engineers!
We made our own ten (10) PCB's with nRF52840 MCU onboard fully according to "Circuit configuration no. 3":
1. LDO only mode (VDDH connected to VDD connected...
I have a custom circuit with nrf52832 which I am trying to program.
All i/o pins seem to be working fine except pins P0.06 - P0.10.
I'm testing it with mbed (digitalout...
Hi,
Thanks for taking the time looking into issue.
We are using Keil uVision 5.14.
Our target is a custom board (BMD200 eval Module based on nRF51822)
We were able to...
Hei guys,
for a new custom board based on nrf52832 where i have to minimize power:
have an external Li-Po battery, with a cutoff @3.0v, so the range will be 4.2v...

Hello,
I used the example ble_app_multirole_lesc and paired with nRF Connect app. However I got the error message (in Bluetooth...
Hi!
So I have my GATT value of a service that I would like to update.
Sadly that value always stays at the initial value.
Below you can find my update function.
