Hi all,
I've developed a broadband vibration energy harvester that is able to pick up uW of energy from just a couple Hz all the way to 150Hz. I'm currently looking for...

Solved: Well, turns out delay and SCK doesnt work well together haha. I imagined the sck signal to be a background thread of some sort. I was wrong.
Hi guys,

The average current during the nRF9160 test DRX is 2.2mA. The period of DRX is 2.56s. Using a China Mobile IoT card. I am testing on the DK board and have turned off all peripherals...
I used NRF24L01 to transmit the data without ACK mode. The receiver received the data normally when only the WR_TX_PLOAD_NACK instruction was used to send the data.If the...
Hello,
I want to set a GPIO Pin to high. Therefore I wrote the code below.
But when the software is written onto the nrf52811, I can not messure any voltage.
I do not...
Hi,
I am going to do data communication between two boards with libuarte. I see that both txdata and rxdata should be uint8_t*. But if I try to transmit the char*, will...
Hi On a nrf9160, I need to send data via UART(E) at 921600 baud. According to the UARTE BAUDRATE register documentation the register value 0xF000000 (Baud921600) leads to...
Hi,
I changed application main.c to enter in to DFU mode after 20 seconds. System is reset every 20 seconds and the boot messages are printed. The message "Booting (0x8200...
I am trying to measure distance with a vl53l1x sensor through the twi_sensor example. I uploaded the code to segger by referring to sparkfun, but twi_handler does not work...

There are some parts of the central implementation that I don't understand.
It is based on cle_uart_app_c.
Isn't the function bl_nus_chars_received_outprint_print_called...
It is amazing how common this error is - there must be 100 posts. Yet none solve the problem and none explain it. It suggests that there is some serious work needed to improve...
I've been developing using nRF52840 using the nRF5 SDK. I have also been using FreeRTOS in my projects.
I recently received an nRF5340pdk to evaluate the nRF5340. I have...
Hi,
The CPU at my target board is nrf52840 and SDk16.
Condition 1: It causes system lock at <-A-> (function of strlen at nrf_ble_scan.c) if I setup the filter of NRF_BLE_SCAN_SHORT_NAME_FILTER...
I am looking to use the nRF9160 in eDRX intervals of 2.7 minutes (no PSM). The goal of the device is to be dormant until receiving a command to begin transmitting its location...
Hi,
I am developing an application based on Connectivity Bridge and I want to establish few simultaneous Bluetooth connections. I am working in Thingy:91, currently on SDK...
Hi,
I got SPI working when writing to the CS pins directly. I thought however it might shorten the SPI acces when using spi_cs_control. When executing the code I will however...
