we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...
I am try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard
Firt I connect to Android device and keep one whitelist.pp_addrs and one whitelist...
I am currently development an app based on the example from the experimental folder using a NRF DK52 as a relay between a central and multiple peripherals.
The app should...
Hello,
Happy New Year.
I'm not able to find nRF52840-QIAA-T or any replacement of this SoC available in the North American market.
I need atleast 5 SoC of the...
Setup: nrf52840 (without internal dc/dc), VDD = 3.3V
Assuming the VDD rail ramps up slowly, the nrf52 will start booting at it's power-on reset threshold of 1.75V (POR)...
Dear BLE Experts, I've followed this tutorial to create a custom GATT service and characteristic. The tutorial seems to be based on the BLE SDK , not the MESH sdk, hence the...
Hello,
Our company is kicking off a project (while we are at the very beginning stage) where multiple nodes (up to 1K) should be connected within a mutual network. I wanted...
We are looking to increase battery life for a product that uses the nRF52832. I'm wondering if it's possible to provide 1.3V directly to the DEC4 pin rather than use the internal...
Hi, I'm referring to this post over 3 years ago: Nordic DevZone (nordicsemi.com)
I'm using Android 8.0, and I'm using SDK 12.3.0 for firmware. I'm trying to create bond...
Hi,
I noticed that when I initiate a chip-erase on the flash-chip and reset the MCU, I'm getting NRFX_ERROR_TIMEOUT's on my nrfx_qspi_init().
I found this ticket: https...
i am using nrf52840 DK with softdevice (s140_nrf52840_5.0.0-1.alpha_softdevice) and applying this throughput example ATT_MTU Throughput Example . and notice that when I use...
Hello I have a problem with the scanning of ble phy coded in Android, I need it to be continuous (or almost) but it seems that for coded it is not possible unlike with legacy...
There are more than one task, after completing the periodic work,the 52832 module should enter system on low power mode,sleep 30 minutes,then wake up and continue with the...
Hello:
I have set the scanning module to search devices by MAC address. It finds the devices that are using a Static Random address, but it cannot find the ones using a...
Hi,
in my project I have a custom board with a nRF52832 chip that reads SAADC data and transmits this data (peripheral role). This data is received by a nRF52840-DK board...
I have an application that is running on using nRF52840 and FreeRTOS. I am considering transitioning to nRF5340. For now, it appears that this also means transitioning from...
