-[[tools:arduino#nordic_nrf5|Arduino IDE 1.8.19]] supports nRF5 micro-controllers and could be a useful tool to develop applications on the micro:bit. 
  
 ===nRF51 SDK=== ===nRF51 SDK===
  
-Version 10.0.0 would appear to be the last SDK for just the nRF51 chipset,  and 12.3.0 +The nRF51 device and its [[tools:nrf51|SDK]] are now obsolete so hardly viable to

-Here is an [[https://devzone.nordicsemi.com/guides/short-range-guides/b/getting-started/posts/introduction-to-nordic-nrf5-sdk-and-softdevice|overview]]. +===Arduino===
- +
-Go to the [[https://www.nordicsemi.com/Products/Development-software/nrf5-sdk/download|download]] page +
-and fetch 12.3.0. +
- +
-After unzipping the following files are found: +

-<code> +
-nRF5SDK1230.zip +
-s130nrf51201.zip +
-s132nrf52310.zip +

-`s130nrf51201.zip' is the BT software stack for the nRF51 (known as the Softdevice) +
-and `s130nrf51201.zip' is the SDK for nRF5x. +
- +
-The Softdevice stack for the nRF52 named `s132nrf52310.zip' is not needed here.+

-===Softdevice===+Zadig is required to provide LIBUSB to the IDE. When using J-Link, this is found as "BULK interface (Interface 2)".
  
-Not sure what to do with this yet.+When trying to flash the Softdevice there will be an error about  
 +fetching the zip file. To remedy this place the hex file in 
 +the Arduino AppData folder.
