Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
Hi, I used the sample code "Master Emulator->2.1.7.8226->Example code->nRFUart"
to develop a new project, and encounter some questions...
we update nRF6310...
Hello,
How many RX buffers are in S110 SoftDevice? I know there are 6 TX buffers (so you can send 6 packets per Connection Interval).
How is it on receiving?
Is it e...
My sensor is off-standard,so I have to use gpio to read and write my sensor.
Gpio IIC will take about 0.5ms to get data.
My app need send data every 7.5ms,it seems that...
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:

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);
