I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
I'm using SDK 12.2.0 with softdevice S130 V2.0.1 and want to use TWI.
Using the ble_beacon example I added the twi code from twi_sensor.
Shortly after calling TWI_Init(...
Hi,
during normal operation, my device shows a power consumption of 4.7mA.
Normal operation is:
accelerometer (lis2dh) detects a shake and wakes up the nrf51 via...
Hii ,
i am using customized board (chip : BT832).
err_code = sd_softdevice_enable(clock_source, softdevice_assertion_handler); hangs. it took some delay and after that...
Hi all,
I have seen a pair of questions ( this and this ) that I think have something to do with this, but didn't find a solution.
I have a custom board with a button...
I want to have an application similar to UART in the SDK example, with multiple peripherals.
I tried to modified existing UART example, but cannot make the central node...
I want to add the nrf52832 to my customized board and I am studing the possibilities for flashing it once that is located on the board. Is it possible to flash trhough the...
I have a board with some LEDs that are driven in the same way as with the nRF51 DK board (i.e. there is a resistor in series with the LED and you drive the pin low to turn...
In our testing we encounter some devices (Centrals with nrf52832), where the peer manager event PM_EVT_BONDED_PEER_CONNECTED contains a invalid peer id 0x4000 (allowed values...
I have a device the uses MSP430f169 and CC2500 RF controller for communication I need to replace the CC2500 RF controller with nRF51422 device.
As I understand an nRF51422...
Hi,
I develop application on MBED platform with NRF52-DK. I figure out that pin "logic" on this board is interchanged. For example. I have LED connected to some pin. When...
Hello,
on my custom board I am trying to use pin P0.09 and P0.010 for interrupt-purposes. So I integrated the necessary adjustments as mentioned in this topic here , which...
Hi,
I develop application using BLE.
In my scenario two NRF52832 operate in two different roles (Client and Server).
I have ready to run app (as server) and can communicate...
Hi,
When I call nrf_drv_spi_transfer to transfer 250 bytes in non-blocking mode, it takes 1.1ms. Is this normal? Any workaround? If it is normal then I have to split my...
My android app give me this "register with gatt stack failed" error on Samsung S7 marshmallow. The scenario is that I am working with 21 BLE peripherals (nrf52). I scan available...
hello dear Engineers!
I Prepare PCB to produce, so have some question about QSPI pins.
According to the "52.10 Registers" , it is possible to Assign any pins to QSPI...
