Hi,my friend,
Now,I use nrf905.Situation is as follows:
I use the NRF PCB circuit of data manual.Nrf905 work, often loss of data.
1.The Product host is to use the stick...
Hi,
I want to use the Blend Micro with more security. I want use a passkey for the Bluetooth connection. For example through the iOS Device.
Is it possible? Static passkey...
How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
For my project I need to send raw data (without prefix or timestamps ) along with system logs trough the same UART.
So far one possible solution is to use NRF_LOG_RAW_INFO...
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...
