Subject: Possible hardware issue with nRF52840-DK (PCA10056) power source switch or onboard debugger
Hello Nordic Support,
I recently received a new nRF52840-DK and am...
We are doing a DFU over BLE with the second MCUboot partition on an external flash. Some times Zephyr can't access the flash after booting, resulting in a bricked device,...
Hey, I am trying to implement ecdh key agreement and derivation, but I am getting PSA_ERROR_INVALID_ARGUMENT (-135) from psa_key_derivation_key_agreement: Any idea what is...
Hi,
I have a question regarding the SAADC timing parameters.
I could not find an official specification for the SAADC power-up time (t_PWRUP). While measuring it on my...
I am using nRF54L10 with nRF Connect SDK v3.1. The device connects over BLE, wakes every 30 minutes to read sensor data, and then should enter deep sleep (System OFF). However...
Hi all — I'm developing a custom nRF5340 development board (Raytac MDBT53-1M) and would value the community's honest read on whether it's worth producing.
The goal is...
I can't get Puck to work.
I did get it loaded on nRF51822-mkit, but
it doesn't advertise (can't see anything on App nRF MCP).
same hardware is working with mbed...
Working on an ANT project.
Switched a project from S210 to S310 to add BLE feature.
For the ANT part, there is no source code modification at all.
Sweet.
This is not...
Hi, I'm porting the nRF8001 library to a PIC, and now i'm having trouble with the setup process: After i get the DeviceStartedEvent the uC starts to send setup messages, and...
Hi,
I did some small applications using RFduino, and now I will start developing using Nordic sdk.
I'll list some features of my application:
a hardware with no...
Hello,
I'm checking the sleep current with nRF51822 DK board, and have two questions.
sleep current is 2.35uA.
In the datasheet, there is only typical value as...
Hello,
as the S310 V2 uses 11k (9k static plus 2k stack) out of 16k ram. We are running into seriouse memory shortage. Is there any chance to that the S310 memory demand...
Hi.
I'm doing a project on S120 Softdevice and in "ble_gap.h" file (included from S120 catalog) i have noticed sd_ble_gap_adv_start() command. I tried to use it but i received...
Hello,
I'm trying to do a synchronization of two devices over BLE. I want to be able to open a scan window only for as little time as possible to receive a timed advertising...
Every once and a while a compile will result in dm_init() returning NRF_ERROR_INVALID_ADDR. Looking at device_manager_peripheral.c:dm_init(), it looks like this error is coming...
Has anyone experience of successful TICK_DV calibration for nRF9E5? What order of accuracy should be achievable?
In my application I maintain a software RTC clocked by...
Hi,
I want to periodically send data through nrf8001 so that once the connection is established for a particular service, i can periodically send data . So how to create...
Hi nordics!
I want to using app_data for preserving data.
For that.
First, I change the value DFU_APP_DATA_RESERVED to "0x0400"
Second, I change the memory start...
I have the "old style" nRF6310 board + nrf51422 boards.
I want to test different examples from the latest sdk, and possibly with different softdevices as well.
I appreciate...
Actually we are facing some problems debugging our custom code using breakpoints and/or single stepping.
Searching the forum I found that using the uart seems a possible...
I was doing some range testing using the ack payload feature of nRF24L01 modules, and I noticed that using different packet sizes would affect the number of packets per second...
