Hello, we are developing a BLE application using nRf52833. Because of the waterproof & stainless steel casing requirement with rechargeable battery charging capability, we...
Hello,
I am working with the NRF5340dk, nrf7002ek, and PPKII. I am unable to get the DK to power up with the PPK. I used a knife to break the trace but for some reason...
Hi,
The attached code is based on a sample code from NCS v2.9.1 and creates a LittleFS flash disk on external SPI NOR onboard nrf54L15DK. There is a mismatch in the code...
Somehow a program I have running on a nrf52840-DK board will enable protection. This kind of screws up the small application I am testing because it seems to lock out the...
Hi,
I am trying to program the custom nRF9160 board using SEGGER JLink/SWD programmer , For same of the boards when connected to custom board and trying to select the device...
Hello,
we are using a nRF5340 with NCS 2.9 and want to signalize a
UART_LINE_CTRL_BREAK
on USB CDC_ACM to the PC.
Is there a direct way to do this?
Many thanks in...
Is there a straightforward way to output the frequency of the 32.768kHz crystal oscillator to a GPIO pin? The motive for this request is to verify the crystal frequency without...
In short:
Is it possible to connect a nRF51822 s110 peripheral from a central without the need for sending advertising packets (by peripheral)?
If (hopefully) yes...
Hello,
I am trying to create an application that sends a notification from the nrf52 to a smartphone when a sensor reading exceeds a certain value. Would the immediate...
Hi,
I have designed and made a PCB with the nRF51422 chip on it. I am programming the chip externally using the P20 header pins on the nRF51-DK. I am not sure whether the...
What I have to do if I met this ? I round length to fit (len+4-(len % 4)). Is it right ?
if (!(IS_WORD_SIZED(m_start_packet.sd_image_size) &&
IS_WORD_SIZED(m_start_packet...
Hello,
We have problem BLE connecting to the nRF52832, if we use the method gap_init(), the "better" smartphones can connect(those who support BT 4.2). If we skip the gatt_init...
Hi,
I'm trying to program an external NRF52832 board with the NRF52-DK, per the instructions in this post .
Programming works fine, but the code doesn't execute after...
Hi,
I'm trying to do DFU in my app, I almost complete it, I met a problem that my app flashed back when I sent 04 to the device.According to the DFU doc,after uploading firmware...
Hi,
I'm using the ADC of nRF52832 on nRF5 SDK V12.2. The setting as attachment. I found that it just do sample one time. But I have use timer to call nrf_drv_saadc_sample...
The scenario like this:
A is BLE peripheral with firmware (ble_app_uart under nRF_SDK_13.0.0_04a0bfd), if no filter,any central can cenncet to it, but I just want B can cennect...
Dear all,
Help please,
I'm evaluating ble_app_uart (Central/Peripheral) but I don't understand how to disable the echo I have on the RTT USB VCP
When I send data from...
I am using 3 nrf52 DKs with S132 and SDK13 to try and implement a combination of the multilink and UART examples. I started with the ble_app_uart_c example and added the relevant...
Hello! I try to use three modules with chip nRF24L01 to syncronize two slave devices by one master device without wires. Required accuracy is about 10 nanoseconds. My idea...
We have an external interrupt every 4ms that collects one 24-bit sample from an analog front end via SPI. After Collecting 6 samples (18 bytes) we send a notification with...
We are obtaining a license from bluetooth SIG to import to the States Bluetooth smart trackers we bought from China. They are made using nRF51x22. How can we find the Controller...
