I am looking to interface PAC1740 to MSP430 conroller. I am planning to connect the BLE in UART. I would like to flash the firmware to BLE through Jlink.
It is written in the design gide that we can flash the firmware to BLE through software debug pins however we can not debug. We can debug onlz when we used Jlink.
And also we need to input 6.8V to VPP is required. Is it comulsory to have 6.8V to VPP pin of BLE.
Do I need any extra circuit apart from mentioned above?. Thank you.
