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 would like to establish communication between my pca10040 and my cellular modem.
Currently I am using ble_app_uart on the peripheral example and I can put messages...
There is the board mark on the chip like n51822CEAAD01350A0, where DO is Build code, 1350 is tracking code(YYMM), A0 is lot code.
My question is how can I get those codes...
I have a thread using a Timer and PPI to trigger SAADC sampling at 100hz. Currently I have an app_timer also running at 100hz to sample the results of the SAADC (and its time...
Hi guys,
I notice that the bytes array of UUID is reversed after registerd.
For example, I define the UUID marco as follows and registe it at ble_nus_init().
#define...

The question I mentioned here
When using ble_gatts_hvx to send data, only send data pointer and length to softdevice, and softdevice did not copy these data to the softdevice...
i used pca10040_debug of bootloader_secure of nRF5_SDK_14.1.0_1dda907.
i created the key by myself.
Bootloader and zip file used the same key.
My device is in DfuTarg...
I'm using an NRF51 w/ S130 operated directly from a coin cell battery. I use the ADC with a voltage divider to successfully measure analog voltages. One of the challenges...
I'm trying to debug a randomly occuring Hardfault. In trying to trace down the source I read the CPU registers use the Nordic hardfault_implementation.c which grabs the register...
NRF52832 reference design BOM did not specify the voltage rating of capacitors. What is the recommended voltage rating of capacitors?
For 32 MHz Crystal Oscillator, specified...
I'm trying to use the TWI talking to a I2C device (LED driver TLC59116). I have some working arduino code which I have converted to use on my nRF52 custom board. I'm using...
Hello,
I'm trying to measure battery voltage on nRF52832 chip using SAADC based on examples/peripheral/saadc and examples/ble_peripheral/ble_app_proximity and noticed that...
Hello Community,
I have a peripheral device which is transmitting the data through custom battery, accelerometer and temperature services.
Now I need to receive that...
