I am looking for cheapest (up to few hundred USD) and simplest Arduino basic solution to track real-time RFID tags distance (also direction if possible) without additional...
Hi all,
I am new to Nordic semiconductor but I could be interessed by nRF9E5. To check if it could fit my requierement, I would like to know if it possible to configure...
Hi,
I am using ADC without external reference and no analog input in order to measure the battery level with a timer (code at the end).
I am also reading several ports...
Hi,
I'm programming the nRF51822 and save some user data into the FLASH by using pstorage_update . It works fine if I set system off mode, and wake it up. I can read back...
Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...

Press "SW2" on beacon and see the LED begin flashing...
I would like to configure the connection timeout with the S130v1. This timeout is described in the following sequence diagram: infocenter.nordicsemi.com/.../group___b_l_e___g_a_p___c_e_n_t_r_a_l___c_o_n_n___m_s_c...
Hi there,
In the process of moving from SDK 10 to SDK 11, I've also been migrating an accelerometer driver over from using straight nrf_drv_twi code to the higher level...
Hello,
Is it possible to use easyDMA to transfer from GPIO to memory without involving the CPU? We need to read from a parallel bus for a short duration, without losing...
When setting up a 1Mhz square wave using NRF_PWM on the NRF52 or GPIOTE on the NRF51 while BLE is advertising, the PWM stops when the radio is active. The problem doesn't...
Hi,
I'm developing a BLE application for the nRF52 and I wish to use directed advertising and the whitelist.
I initialise the Bluetooth advertising using the following...
I have been using softdevice S130 version 2.0.0-7.alpha with SDK 11 in Keil using the pack installer. How do I change my project to work with the updated version that doesn...
Hi,
I believe there's a minor bug in low_power_pwm.c regarding pwm_state.
The routine low_power_pwm_start sets the pwm_state to NRF_DRV_STATE_POWERED_ON ; but it then...
I've a PCA10036 V1, I change the IC to nRF52822 QFAA-B016. With nRF5_SDK_11.0.0-2.alpha_bc3f6a0 and SD: s132_nrf52_2.0.0-7.alpha_softdevice, the programme started but if I...
I am troubling shooting some issues between my device and iPhone using nRF Sniffer.
One of the errors the sniffer captures is this:
Master to Slave: Rcvd Read By Type...
I will be using the nRF52 adc from -20C to 85C and am trying to determine if I need to calibrate and if so how much temperature difference I can have before it is time to...
Hi, I'm working on the nRF52 with S132 v2.0.0.
I am using a self-implemented "connection manager" that tries to establish bluetooth connections to pre-configured auxiliary...
Hi,
I am using 2 x AA batteries which gives 3V. Planning to enable all the internal LDOs (1.2V, 1.8V and Radio LDO).
VDD and AVDD are shorted on Board.
Will the device...
Is there a porting guide to this?
Custom hardware

I'm getting a reset in client_handling.c::ble_stack_init();
Right after I set the clock as...
Even I am writing BLE applications, but I don't totally understand these items:
