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...
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...
Hi, We designed a board using NRF5340-CLAA-R by following the Altium Reference design. Although when we tried to place an order with JLCPCB or PCBWAY, then informed that they...
Hi, I am pretty certain I have used RTTViewer before on the nRF9160, albeit not frequently. I cannot remember if I only used it on custom nRF9160 boards or if I used it on...
hello,
on our bm833 dev board, I scope (using a PIO) the time it takes for the bt_nus_send function to send 146 BYTES. The PIO goes to 0 after the callback nus_sent_cb has...
Summary
We are developing a Central application on the nRF7002 DK (nRF5340 SoC) using NCS v2.7.0 . The goal is to establish and maintain 11 concurrent Bluetooth Low Energy...
We're working on a project that interfaces an nRF9151 with a BQ40Z50 from Texas Instruments (via I²C / TWI / SMBus), and we've noticed the communication is unreliable. The...
Hi,
We are currently working on power optimization and want the device to wake up from the System ON state ( PM_STATE_SUSPEND_TO_IDLE ) using the RTC0 timer. However, I...
Trying to prototype a pinout on the nRF54L15 dev kit. We want P1.02 to be a GPIO pin instead of NFC. We followed the instructions to recover the device which erases the UICR...
Hi,
I am facing the following issue when i am calling west build from gitlab runner.
west: unknown command "build"; workspace C:\ncs\v2.5.0 does not define this extension...
Hi,
I am trying to come up with a different approach to SED reattachment using a backing off MLE session. Is there a way for the SED to keep on the polling even when in...
I'm working on an nRF9151 application that periodically sends small UDP packets (20-40 bytes) over both terrestrial LTE and satellite NTN networks. The device uses PSM between...
Hi,
We are doing some RF certification testing, EMC and also FCC, and wondered if you had advise on setting the modem on and transmitting, potentially if there is some...
Hi there. I have been working on a small project where I am using an encryption library for communication over ble. I am receiving encrypted token over ble charcteristics...
Description: Hello,
I am integrating a Protocentral MAX30001 ECG sensor with the nRF52DK (nRF52832) using the nRF Connect SDK v3.1.1.
The Issue: The sensor hardware is...
Hi,
I'm developing a Matter device based on the Window Covering sample. I have added another endpoint to the device containing some sensor clusters and it all works after...
Hi,
I am looking for a constant-time memory comparison is a function that compares memory for equality in a fixed amount of time, regardless of the data's content. I am...
