I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
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);
in...
Hi,
Can the value of NRF_RTC1->COUNTER be read safely from the main loop without first stopping the RTC or temporarily disabling the RTC1 interrupt etc? (nRF51822 or nRF51922...
I used the nRF51822 Evaluation kit and flashed the BLE_proximity example on to the PCA100001 board.
In the master control panel the USB dongle measured -46 dBm(Nordic_prox...
