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...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
Hello all,
I would like to ask you something,
I've done all my development with NRF24L01+ but now I have some NRF24L01 modules.
I know that NRF24L01+ is fully compatible...
Hi
I am created one more timer in ble_app_hrs
like in timer_init()
err_code = app_timer_create(&m_current_timer_id,
APP_TIMER_MODE_REPEATED,
current_timel_meas_timeout_handler...
I'm a little lost on the GPIO mappings from the code to the outside world. I'm playing with the UART example on the nRF6310 board. In the sample code, IO 16 is RX and IO 17...
Hi,
I am using ble_app_hrs application as a reference code.
in our case i have gpio interrupt for every 25 ms.
what should i keep BUTTON_DETECTION_DELAY for 25ms...
Does the lcd clobber the tmr0 and/or ANT ???
We just went through several days of working w/ ns on running ANT w/ RTC with a resolution of using sd_ calls.
Is the LCD...
Hi,
i am using nrf51822 custom board.
For our application i am using ble_app_hrs source code.
in that i have gpio interrupt for every 500ms, to get data from accelerometer...
For example, if I have a GPIO pin configured with low sense, and it goes low just before I call sd_power_system_off(), will the device return to System ON mode immediately...
Hello,
I've got a nRF51822 DK which I try to program with a SoftDevice using the nRFgo Studio (nRF51 Programming). My chip/programmer seem to recognized properly since...
Hi,
For developing our application i am using ble_app_hrs
in my case i have gpio interrupt for every 500 ms to get data from accelerometer.
question:
in heart...
Hi,
I am attempting to understand the timing of events when a mobile application connects to my nRF51822 based device. The reason being is that I have to enable the UART...
Hello,
Greetings, in the nRF24L01 datasheet, its mentioned that the module can work as a multiceiver, meaning 5 nRF24L01 module acting as PTx can communicate with 1 nRF24L01...
hi,
my customer using nrf51822 DK to have debugging software,the error occur in the attachment.
can you tell me something have Caused this problem?
thank you !...
I am using the code
err_code = sd_ble_gap_device_name_set(&sec_mode, (const uint8_t *)deviceName, nameLen);
I have made sure that nameLen is less than BLE_GAP_DEVNAME_MAX_LEN...
Hi
i am using twi_hw_master.c for i2c communication of accelerometer.
my accelerometer address is 0x18.
once i call
twi_master_transfer(0x18,dataW,1,1);
