Hey!
I have an isp1807 test board, which uses an nrf52840 chip, and an isp1p807 programmer (ISP130603E). Currently, my code is written using the nrf52 sdk v17. When I am connected and powered off the programming board, the test board boots up correctly and is able to connect to a tablet via Bluetooth. However, when I power the test the board from an external power supply, the mcu crashes on Bluetooth initialization. I was wondering if anyone has had issues powering the nrf52840, off an external power supply?
Thanks for your help!
