technical information for the ISP1507 module (the chipset is nRF52)

[Luca Taruffi]

I need some technical information:

- the micro Host can (through a pin?) make WakeUp of the BLE module to configure it / change the operating parameters etc?
- the BLE module can make WakeUp of the micro Host (via a pin) when a mobile device wants to communicate with the product?
- when the micro Host and the BLE module are active, can the micro Host exchange data transparently with the mobile application via virtual serial port? (emulated port)
- the device is programmable only via JTAG port, or does a pre-loaded boot loader exist?

Hi,

As mentioned by awneil, I can only answer based on the core IC. Module vendors can do whatever they want with the ICs in their modules (preloaded bootloader, preloaded special FW, etc.)

• The nRF52 series is a System-on-Chip, meaning that Radio and CPU is embedded into one chip, with embedded flash and RAM. The application and protocol stack (BLE software stack) will run on the same CPU core. The CPU have two idle modes, system on and system off. System on can be used together with BLE when there is no CPU activity. It will wake on any event. If in system off mode, the CPU can only be waked by GPIO, NFC, RESET or analog input (LPCOMP).
• There is example in our SDK showing use of pin interrupt. This can also be used to wake chip from system off sleep mode.
• There is a UART over BLE application in the SDK.
• The chip is programmable over SWD interface. We provice bootloader in our SDK, but the IC come blank from factory.

Best regards,
Jørgen
