Good day,
I've developed a board with a MDBT50Q on it. I'm using the Reg0 DC/DC and LDO Mode Disabled reference circuit ( https://www.raytac.com/download/index.php?index_id...
Hi,
I have the issue that my Zigbee device reports the error "Production configuration is not present or invalid (status: -1)". I followed the guide from this( https://docs...
Hi,
I am using an nRF52840 as a Zigbee NCP. I have built the firmware myself using nRF Connect, and I am also running MCUBoot. Sometimes after some usage, the chip starts...
Hello everyone,
I am testing out I2C on the nRF54L15 for a custom PCB project.
I first tested a simple mpu6050 sensor on &i2c21 on pins P1.11 for SCL and P1.12 for SDA...
I have a bit of an unusual use case where the nPM1300 is quite ideal but need to use an external charger for the battery instead of the internal charger. The nPM1300 fuel...
Hello,
We are currently developing with the nRF9151 and would like to request more information regarding GNSS SNR testing.
We have reviewed the documented GNSS functionality...
Hello,
Is the nrf54 family's I2C peripheral compatible with I3C? I need to communicate with several I3C sensors on the same bus.
If yes, is the software support only...
Is it possible to put the nRF52 into recieve only mode (say through direct test mode) so that the input impedance can be measured using a VNA? Is the input impedance of the...
When I initialize PPI after timer1 has been initialized I get a fatal error (and reset).
Code:
const nrf_drv_timer_t timer1 = NRF_DRV_TIMER_INSTANCE(1);

Hello,
we were measuring sleep modes and it consumes around 1.3uA which is correct.
But when we needed to be woken up on edge we found out it consumes extra 8uA! Are you...
Are there any nRF51 demo firmware implementing paring function that the central and peripheral devices will connect automatically without user interaction when they come ...
i am working using NRF52, s132, sdk11, freertos.
for fft , i used "arm_rfft_fast_f32(...)" in cmsis-dsp library.
and i inserted a fpu interrupt.

Hi.
I'm using PCA10040.
I'm trying to control GPIO.
But I can't control PIN 09, 10.
Let me show you my source code.

I need to turn off a GPIO after 8 hours of it being triggered.
I was reading about changing the prescaler to allot for 8 hours. I did the calculations and came up with a...
I have purchased a red bear lab ble nano board with nrf51822 and a PICTAIL board with microchip RN4020 chip. i have set Tx power 4 for both boards. The rssi value shown in...
This may just be a preference or architecturing question but I thought I'd ask in case there was anything I'm not thinking of, or benefit of one or the other.
I have 2...
Hello,i am find an interesting phenomenon recently.I have a Nordic 5182 device(role as peripheral) and bonded to an iOS device(role as master),when i put the iOS device near...
I'm wondering, is it possible? This is what I think it will be like if it were going to be implemented:
Acquire the firmware from a host somewhere.
Since the payload...
Is there a function like battery_level_in_percent for AA battery?
I know battery_level_in_percent is only for CR2032.
Even though I compensate it to make it 3V from AA battery...
