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...
Hello,
I am trying to build a single device, lets say loaded with firmware "A".
I would like to have two of these devices, both with firmware "A" to detect proximity...
I can't find anything to indicate for sure that the S120 BLE softdevice will work on the nRF51422 BLE/ANT chip. I'm pitting BLE vs ANT for my current use case and being able...
nRf51422 flash data retention is 10 years at 40°C. We need for our application (motor control roller shutter) 20 years. What can you do to increase this value?
Hi All,
Please correct the following in my understanding. Also , i am planning to build a
remote controlled device using a PWM output. How does ATT,GATT and GAP affect/influence...
Hi.
I have just a question:
Can the same device work with gazell protocol and bluetooth LE alternatively?
I want a net with a host and some devices, but host must be...
I've somehow lost the ability to perform over the air DFU from Master Control Panel.
I have reinstalled the J-Link drivers, nrfgo studio, I've flashed the PCA10000. I can...
My board works most of the time are very good，but one time i power down the board when ble connecting and data transmitting，the board can't work when power on.and i can't...
Hello,
I am trying to use ble_app_uart example from pca10001 to nrf6310 board from development kit. My nexus 7 detects the BLE device as 'Nordic_UART' but disconnects immediately...
Posting this as separate question as it got no traction in the other thread:
Why are there many of the same include files in the DFU example directory as in the S110 7...
Hello everyone!
I'm currently developing a project in which I require a remote control (touchscreen TFT + arm MCU) to send and recive some data over a bluetooth connection...
Hallo
We want to update the firmware over the air (BLE).
What is a safty concept?
Our firmware need about 60KB flash ROM.
What have we to calculate for BLE software?

Hello Everybody,
I have a question about nRF51422. I want to monitor the ANT+ message from any sensor, which is already connected with the device,
Scenario : if it is...
Hello,
Im trying to create a synchronisation method for sensors using BLE. At the moment i can synchronise them within 10ms accuracy, in theory it should be within 2ms...
