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:

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_...
