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...

hello,
I've encountered a problem with our own nrf51822 circuit not advertising.
Our circuit is exactly the same as what is given as the reference circuitry on the datasheet...
It's the first time i'm using the spi to connect various slaves, so is there any example how to communicate a raspberry with 2 or more nRF24L01 on the same bus?
Thanks in...
