I am getting get BLE_EVT_USER_MEM_REQUEST and BLE_GAP_EVT_CONN_PARAM_UPDATE event, when writing to ble device, sample code did not handle these event, and seems no document...
Hello:
Why do I erase SDK5.2 version of flash and read not, in SDK4.2 can. I tested nrf51_sdk_v5_2_0_39364\nrf51822\Board\nrf6310\flashwrite_example is a good example.However...
before i write the flash, it has been erased.so ,its value is all 0xff.
when i write 0x00 to flash address 0x0001,the value read out is not 0x00 but 0x01,and the value in...
I'm looking for a way to use the nordic uart service ( devzone.nordicsemi.com/.../ble_sdk_app_nus_eval.html) from Linux using the native Linux BLE Stack (BlueZ). My application...
Hi,
I've created an application using the S110 experimental ANCS demo. I successfully implemented ANCS and then began to structure my application around it. At some point...
Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
We have an application that requires a fairly quick disconnect (under 250msec) when the RSSI exceeds a threshold, for example -80db. Unfortunately, around 1 out of every 4...
I am trying to program a nrf51822 module using the nrf51-dk.I have made connections as per the nrf51-dk user guide, but sme is not working...

Hello! Developer,
Does anyone know how to transfer and store the value as big endian on memory address on nRF51 and send it over BLE to display value on MCP as big endian...
Hello!
I'm trying to get the 16 bit ADC value as 2 of 8 bit array from nRF51 development kit over bluetooth to MCP, but when it displays on the MCP the value is "swap"...
Is it a good idea to use nRF51 standalone as an Application Processor and also as BLE connectivity chip?
OR
Is it a good practice to use a separate Application Processor...
I have a question on - to me - seemingly weird behavior about copying data out of the event from the soft device.
Situation: I have a 32 bit integer characteristic which...
Hey all!
Newbie here. I developed and tested some code on an NRF51DK easily enough using mbed, and now I'm trying to put it onto a PTR5518 module from Xuntong (which I...
Could you rub my nose in Bluetooth SIG Core or just explain what does chip do when switching to very noisy channel? For example Wi-Fi working very close to our device.
Hello:
I have read the documentation but I cannot determine if INPTR and OUTPTR can be set to the same memory address? I will try it to see what happens but it would be...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
