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...

Dear,
Im trying to measure the RSSI with THINGY:91, I found on the document nrf91_at_commands_v1.1.pdf about
1. AT+CSQ
+CSQ: <rssi>,<ber>
Note: Not detectable, RAT...
Hi!
I am currently working on a project where i would like to use Thingy:91 as MCU board as it contains other features i need to use, like 4G and GPS.
The problem is that...
Hi I'm currently develop new product based on RAK8212. I have problem with reprogramming devices. Programmer i use is nRF52-DK I'm not able to reprogram about 10% of devices...
Hello,
I have a low power application, which is activated by a push button press. (The DC-DC converter is also in shutdown mode normally, so the NRF9160 does not have power...
I am occasionally (very rarely) getting "Mesh assert at 0x00037996", but when I try to look this up, I get:
My understanding is that this means the mesh_assert is...
Hello, this is the nrf52833/52820 design drawn by the customer, because this is our first contact, please help to check whether it is reasonable? thank you.
Hello,
I'm working on a BLE app on an Arduino Nano 33 BLE, which is equiped with an nrf52840. I'm struggling to increase my BLE transfer speed ( i think due to the limitations...
Actually i was working on 3 boards, nRF51422,nRF51822 & nRF52840. While executing some examples on each board i realised that each board has its specific pca hex file to be...
I n the main of my program I have this( UBLOX_PWR_PIN = Pin16 of nrf ),
uart_init(); nrf_gpio_cfg_output(UBLOX_PWR_PIN); nrf_gpio_pin_set(UBLOX_PWR_PIN); nrf_delay_ms(200...
Hello,
I've a problem with a PPK board.
When the current go over 10mA the value reported is wrong, in my case should be 15mA and PPK measure 80mA and more. Instead, in...
Hello,
I am working on a project that is using nrf52840 chip as a peripheral and the product is supposed to last and run for 25 years. During that period the device will...
Hi everyone I have been reading the GPS data using nordic nrf52840 over the UART. I am able to receive as much as 64KB of data via the UART. Here's the scenario of whats been...
Hi All:
Applyed the under timeslot :
causes some peripherals(eg:static const nrf_drv_timer_t m_timer = NRF_DRV_TIMER_INSTANCE(2)) n o access interrupt,
what 's the...
I am trying to get the maximum Tx power from the nRF5340 PDK.
The nRF5340 specifications say that setting VREGRADIO.VREQH is required to get the last +3dBm of transmit power...
