I was wondering would it be possible to use a 50 ohm IC Antenna ( like this one ) for the nRF51822 with the matching circuit given for the nRF24 ( link here )?
It seems...
Hi,
Is there any difference(data rate) between sending large data packets through single characteristics and multiple characteristics?
I have created one characteristic...
Hi everone!
I need to get a timer setup which repeatly fires 2 IRQs. The first i.e. after a timer count cc0=500 and the 2nd count cc0=700. After 700 ticks the timer value...
Hi,
I've noticed that when using SPI without a Soft Device or BLE function calls, the SPI peripheral is easy to control and operates correctly.
This nice operation stops...
hi,everyone.

I can't seem to find the required current of NVMC doing erase and write. The product spec has only timings but not more. Could someone from Nordic provide some figures? Experimental...
Hi,
I have a C# app connecting to 51822 devices, doing data/firmware download. When I try to send erase page command (before write), erase works, but there is a disconnect;...
Should we keep track of this by monitoring the write events or poll the gatts value via the softdevice?
It looks like it's faster (+shorter = less consumption) to monitor...
