2)message queue should be used or any other ipcs can be...
Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
Hello there, I'm developing a device who will use two NRF52832(ANNA-B112 Module). They will communicate as central and peripheral. But i'm facing a problem, i need to after...
I could decrease current consumption at v1.2.0, but couldn't at 1.3.0. 520uA flows in k_cpu_idle();
How can you do that?
Also, in v1.3.0, CONFIG_UART_0_NRF_UARTE is depricated...
Hello
Good day!
Problem: We have got a new nrf52DK, and in our application development we use GPIO interrupts (we have set up 4 gpio interrupts). Surprisingly the GPIO...
Hi,
I'd like to know the units of measurement of the data obtained by the environmental sensors of the Thingy:91 device. I have found no information on that.
Temperature...
Hi,
I am currently working with the asset_tracker example and sending information by LTE-M of environmental and GPS data. I wanted to know if there is any way to calculate...
Hi,
I want to test eddystone example with nRF52833.
The default project doesn't include PCA10100.
I am trying to create one, but it always stuck in the function nrf_crypto_rng_backend_init...
I believe from reading some of the existing posts that my JLink EDU mini programmer (with SWD connection) should work with the nRF51822 (it shows up as a device option in...
Hi,
I want to build a bluetooth central example of zepher to nrf52832.
I am using the command "west build -p auto -b nrf52832_mdk samples\bluetooth\central" to build the...
I'm using 51822 QFAC, SDK11 S130 2.0.0.
I'm able to write to flash using fstorage_write() below. But the problem is whenever I put a for loop after I call fstorage_write...
Hi,
I built a simple custom board with an nRF52832 ebyte BLE module with no added components except for the RST and DFU buttons, the serial wiring are the same pins (RX...
Hi,
I'm working on a BLE scanner which need collect data from the beacon's scan response packet.
As far as I test, the current mesh beaconing example cannot get the scan...
I plan to use nrf52840 in high voltage mode (connected directly to the power source via VDDH pin) with button.
And I plan to use voltage regulator with EN pin (with pull...
The most relevant thread on this topic is two years old. I do not want to use Keil as it is so costly and the project may not go anywhere. I am not interesting in using the...
Is it possible for me to easily modify the nrf52 Zigbee samples to run on 1 or more of my 5340 M33 cores, or is it a rewrite?
I can see chip support for nrf52 but no mention...
