Pinecil V2 firmware upgrade


To upgrade the firmware for a Pinecil V2 I had to obtain blisp, the flashing utility, and the firmware itself (IronOS).

To flash I needed to put the Pinecil in flash mode:

Long hold the - button before plugging the USB-C cable into the back of the Pinecil. Keep holding down the - for ~10-15 seconds after plugging in the cable, then release the button. Pine64 wiki

The all I had to run was this command:

sudo ./blisp write -c bl70x --reset ./Pinecilv2_EN.bin

Now my Pinecil supports Bluetooth. Not something I strictly need in a soldering iron but given it has the hardware why not installing the software that can use it?
