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,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
I may be missing something. I am trying to generate a square wave from a GPIO pin in a BLE application (SoftDevice 8.0). I tried libraries (nrf_pwm.c and nrf_pwm.h) in this...
Why does the nRF52 only have +4dB output when most competitor chips are atleast +6dB (some up to +10dB). I understand that the RX has been improved by 3dB for a better overall...
Is there a way to know that there is no more data being received via UART?
One solution is, of course, to start a timer every time a byte is received via uart_evt_handler...
I am using read characteristic to read data from from a characteristic. The characteristics range from 2 bytes to 32 bytes in length. The time to read the data using IOS,...
For those of us who were not invited to Norway to try the nRF52 over the next two days....
When and how can we get our hands on a nRF52 development kit?
For example, ble_advdata_set() wants to insert company identifier and a "00" in the last byte of the response packet. Are these required, and if not, how to use the ble_advdata_set...
Hi there,
One quick question about updating Beacon configuration, including UUID, major, and minor. For development, we can use our APP on the phone or Master Control Panel...
I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
I'm currently testing a custom board using BSP_SIMPLE defined in my board header file.
This is failing to build due to undefined BSP_LED_APP_TIMERS_NUMBER.
Appears to...
I have added a power amplifier in nrf51422, but I don't know when I should enable/disable the power amplifier in order to reduce power consumption, i.e. when listen for scanning...
Hi,
I try to compile example application (ble_sdk_app_beacon) and I have error on linking objects.
