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...

I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
Hi,
I tested the nrf beacon application, it allows only the beacons with company identifier 0x0059 (nordic's id). But i need to modify it to support all the device, how...
Hello,
I have a couple of questions about sending multiple notifications:
I want to send multiple notifications (from same characteristic), is that allowed by...
Looking at the AN36 code, i notice that in the APP_SCHED_INIT define, for the argument EVENT_SIZE is used sizeof(app_timer_event_t) . In the meantime, the scheduler is used...
Hi guys,
I was wondering if the nrf51822 can listen to data packets being sent over by the nrf24. In the datasheet they say it supports nrf24 protocol. But what exactly...
I have a nRF51822 module programmed for custom service and characteristics. I am able to connect to this module using android 4.3 API. I can get characteristics and their...
First of all, let me say that I've read some of the other topics, and I clearly don't belong here haha. I'm not at all knowledgable about electronics and the inner workings...
I wonder if a couple (or three) of your module with PCB antenna as receivers could be used for triangulating the transmitter, could I have some hints about this, or a schetch...
Just putting this here in case anyone else comes across this issue, esb_arm.lib and gzll_arm.lib don't appear to implement the work-around in PAN 18(in the version I tested...
Hello, I would like to know if the adress byte that is transmitted after the preamble is the MSB or LSB.
I've read the datasheet's page 28 and it's not very clear, it just...
I need to have an iOS device send my nRF51 some commands, some settings, and retrieve some data, not at regular intervals. The nRF51 should only-speak-when-spoken-to.

Hi,
I am using the NRF51822-CEAA flip chip package for my custom board.
Because this package has an optical vulnerability from the sides, could you please advise how...
