Ok this is starting to get very frustrating. I have updated firmware before ok but for some reason now the puck0js won't stay in bootloader mode. That is I hold the button insert the battery release button and LED turns red. It stays red for about 10 seconds then turns off. Or if I am very quick and try to connect to it using nRF tools it will also drop out of bootloader mode.
What the hell is going on. I have not touched the puck in months (family issues to deal with) but I am pretty sure it was on firmware 1.90. I want to update to the latest 1.93 but cannot if I cannot get the damn thing to stick on bootloader mode.
Any ideas?
