I am getting get BLE_EVT_USER_MEM_REQUEST and BLE_GAP_EVT_CONN_PARAM_UPDATE event, when writing to ble device, sample code did not handle these event, and seems no document...
Hello:
Why do I erase SDK5.2 version of flash and read not, in SDK4.2 can. I tested nrf51_sdk_v5_2_0_39364\nrf51822\Board\nrf6310\flashwrite_example is a good example.However...
before i write the flash, it has been erased.so ,its value is all 0xff.

I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
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...

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...
Hi Nordic,
I am testing the sensor LSM9DS1 with the nrf52840. I try to make one pin attach to handle the interruption for the FIFO full interrupt.The FIFO handling function...
Hi everyone,
I am trying to understand the concepts of ATT MTU and DLE, so let me share my thoughts along with some questions. Maybe this is useful for other community members...
