We are considering using Gazell for an outdoor application, i.e. lots of noise and disturbances, constantly changing environment, where the amount data being transferred is...
Hi everyone,
I have found your git "Ble Optiboot"( github.com/.../ble-optiboot) , and I have understood, it is usefull to load a binary into MCU flash, I was looking for...
I'll go ahead and describe what I need to do and see if anyone might have some place to start for me since I'm having a lot of trouble figuring out what I need.
I'm looking...
Hello ,
I'm designing an embedded system with one of your RF chips (NRF24L01+) and as far as I searched for the datasheet , It seems like NRF24L01+ doesn't have a hardware...
Hi,
This post is very old.

I have a nrf51822 chip and I'm using it as BLE and it exposes some service and characteristics and it is working...
Hello!
I set up a project using NRF24L01 and a patch antenna ceramic, the type used in GPS.
In fact, I tested several types of antennas, F, F inverted, GPS, Loop. But...
Hello,
I'm trying to create a PC application to read out some Ti Sensor Tag modules. I'm using a nRF51822 USB dongle and the Master Emulator api.
The nRF dongle sees...
Hi all,
I'm having problems when linking my code intended for use on the nRF51822. For some reason there are missing symbols that are needed. I've traced the dependencies...
Hello,
Does Keil's Lite/Evaluation MDK-ARM tool chain version suffice for development work on nRF51 devices? Please advise!
I have seen questions about using GCC and...
I'm using the s110_nrf51822_5.2.1_softdevice with the NRF51822. If I understand correctly, after pairing the NRF51822 with a phone, a long term key has been generated and...
Hello,
I decided that bonding (does it equivalent to "pairing"?) is not allowed in my application, so I modified the following definition in main.c:
#define SEC_PARAM_BOND...
We are trying to get the ANT feature to run based on RTC as follows:
a. Timer RTC0 or 1 (1 for this example - tick is disabled, compare is on.)
b. Timer initialized (all...
Hi,
I'm a new learner for the nrf51822. In the SDk ,there is an example of esb which is used for the radio transmittion with ACK. I want to know that if I can use the esb...
We have a custom board designed based on N51822, CEAAB0 and we have used the chip antenna from ST BAL-NRF01D3. When we have flashed our proximity code to the device, we will...
Hi,
After i use sd_ble_gatts_hvx() ,i will receive a BLE_EVT_TX_COMPLETE.
The "tx_complete.count" is no problem when i use softdevice 5.2.1 . e.g. count =1. this is correct...
Dear Sir,
i am using pca10001.
Actually i tried to read and write the data from EEPROM having address 0x50 though i2cbus.
i made po.0 and p0.1 as output pin then...
Hi,
I've created a small test program (pasted below) that is intended to help me profile some of my code down to us resolution. Maybe you can quickly run it (no other files...
I'm designing a board using the nRF51822 and leaving test points on the PCB for the programming/debug lines so the chip can be programmed after PCB fab. Are there any reference...
I'm evaluating nF51822 for my application which needs to wake up from either a button press or an interrupt pin singal from an accelerometer. Normally this can be done with...
hi guys, i am writing a code for reading data from a sensor using twi interface, the twi is not working properly, here in SDK i found two examples of twi - sw_ nd hw_ is sw_...
Hi all,
I have read the nRF51822_PS v2.0 and know that nRF51822 supports the SPI slave mode,so I want to know whcih version of the chip will support it?
Also,I have...
