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...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hello,
I am using the Thingy:91 PCB and I have disabled the nRF52 by cutting SB4 and soldering SB3. This makes me unable to log through UART. For this reason I implemented...
To the kind attention of Nordic support team,
I need to disable, enable gzll more times. When enabling it, code gets often stuck in my case as in figure: nrf_impala.c 442...
I have achieved Bluetooth connection between 1*ble_central<------>6*ble_peripheral.
But, ble_peripheral sometimes upload data at the same time, then sometimes lose data...
We're successfully using nrf_crypto_aead_crypt() with AES CCM, a 128-bit key, a 64-bit MAC, and the NRF_CRYPTO_ENCRYPT operator to encrypt some data and generate a MAC that...
HI, all,
I am trying to transfer my previous project from nrf51822 to nrf52840, and at very the beginning ,I can not make the UART/UARTE of nrf52840 work.
0, I have programmed...
Hi, everyone,
I am pretty new to nRF52 development. Right now, I have an issue with the SAADC trigger by RTC, which I follow this example . The issue that I have right now...
Hey all,
Here's another question. Many of the examples in the Nordic Connect SDK are rather large. Transferring them with MCUmgr at 115200 BAUD takes sometimes more than...
Hi
I am testing sending and receiving data between nRF51 dongle and peripheral by example of heart-rate-collector.
now I could find characteristics I need(write, read...
Hi all,
My application is as follows:
I have an android app which will send some data to a nRF DK. The data I want to send is in HEX characters between 0x00 to 0xFF. And...
Hello,
For nRF51822 and nRF52832, I'm using GPIOTE, PPI and timers to measure the duration that a pin, which is normally low, goes hi (typically 100-300 milliseconds). I...
The following questions are in regards to the instructions at nRF_Connect_SDK-modifying-a-sample-application .
In the Windows environment, I am transitioning from using...
Dear all,
I recently made a custom PCB using the aQFN73 package of the nRF52840 and, even though I respected the antenna constraints (but in 2 layers) I get no signal whatsoever...
Hi Devzone:
I am using P0.00 as SDA and P0.01 as SCL on nRF52833, And I got waveforms like below when I am doing I2C transactions:
the red waveform is SDA and the green...
