We are trying to evaluate nrf9151 for working with Soft-SIM. Are there any instructions for configuring the Soft-SIM through AT command mode, or do I need to use another mode...
I was doing some developement for a custom board on NCS v2.9.1 when i noticed some of the changes i was making in my prj.conf weren't being set in the application. My impression...
In my circuit I have a MOSFET which disconnects the battery. There is a GPIO pin which turns this device on and I'm using regulator-fixed to drive it during start-up. A short...
We are currently using ncs 2.9.0 on an nRF5340. We use the BT_HCI_OP_VS_READ_VERSION_INFO to determine at runtime what version of the BLE stack is present. This information...
Hi I'm trying to load a custom board with nrf9160 with the Serial LTE Modem, and route the AT commands to the UART from a coprocessor (ESP32C3) I have followed the guide on...
Hello,
we have a working system on the nrf9161 that works without zephyr. We have our own secure firmware that successfully uses the cc310 after we start the actual application...
Keep hitting my head on this inconvenient workflow.
Edit build config
Select target custom board
Build config
All OK
Edit config again
Target board has been...
I've been using nRF24LE1 for development. The HAL library provide the AES encryption for ECB mode. Now I need the decryption function. Does anyone has the realization? Any...
Hello everyone,
I use SDK14.2 and s132 softdevice. I can read "NRF_SAADC_INPUT_AIN0" and "NRF_SAADC_INPUT_VDD" pins and system is working properly.
Working Code like...
Dear friends,
I am using the nRF 52832, s132. I want to know the BER (bit error rate) of the BLE link. How can i measure it? Further, to what extent do other radio interferences...
Hi.
I want to know the time difference between functions by using a timer instead of a difference. I've looked at app_timer.h, but it's hard to understand.
I do not need...
I am trying to use the ADC to take power measurements on an interval. I found an example to read the values out online:
void ADC_IRQHandler() { nrf_adc_conversion_event_clean...
I am designing a PCB using the NRF52832 and this antenna . The antenna design guidelines suggest ground clearance and direct traces from the NRF52832 to the antenna without...
I am working on a project which I wish to Paer between to nRF51422 devices and to use the auto reconnect between them. there won't be any display so it must be automatically...
Hi,
is it necessary to use internal regulator for NFC DC/DC or we can use normal internal LDO in design.
also if we need to use internal DC/DC regulator, what is the...
Hi, I have tried to find a solution for some time now in the Nordic Semiconductor forms.
We have been noticing a peak or a disturbance in voltage in every connection interval...
I have encountered a scenario in which my application is terminating the BLE connection via a call to sd_ble_gap_disconnect, while around the same time I receive a write request...
I'm able to successfully use peripheral/uart example to read the data from GPS module. I achieved the same by setting baud rate to 4800, and connecting rx and tx of GPS to...
Hi,
Question about FOTA (firmaware upgrade over the air).
I know that nrf52832 has 512 kB of flash, and the ble stack( softdevice ) has 136 kB , and the bootloader has...
Hi,
I put my NRF52 to sleep (POWER OFF mode) and configure it to wake on GPIO port event like so:
This GPIO is set up on a reed switch. Occasionally, the NRF52 will...
