Do I have to use the Segger branded debugger to program over the 2-wire SWD interface (JTAG) of the Nordic-based modules?
Yes, any programmer/debugger that supports the SWD 2-wire interface and the Cortex M4F processor should work with the Nordic-based modules. You can find information about the memory map in the nRF5xxxx Product Specification under the Memory and NVMC sections.
Is it possible to use AT commands to configure BL651?
The BL651 cannot be configured using AT commands, as the AT command set available with the BL65x modules requires loading a smartBASIC Application. Because of the limited Flash and RAM available on the BL651 it cannot support the smartBASIC firmware and therefore, the AT Interface application cannot be loaded to the module. It must be programmed using any of the developer platforms that support working with the nRF52810, such as Nordic SDK, Zephyr Project, or MyNewt, among others. All of these platforms require flashing the BLE application via the JTAG Interface, therefore it is required that you bring out the JTAG interface in order to program the BL651 module for BLE operation.
Is there a DVK for the BL651 module?
We do not offer a DVK for the BL651, however, as the BL651 and BL652 are pin for pin compatible, the DVK-BL652 can be used during development as the development platform. It is important you keep in mind that the BL651 has half the flash/RAM so it cannot support any central role functions such as scanning and initiating connections, and it is not capable of supporting smartBASIC firmware, therefore it will be necessary to flash the DVK with custom firmware, via the JTAG interface, based on the development platform that you elect to work with.
BL651 software development can be completed with any platform that supports working with the nRF52810 such as Nordic SDK, Zephyr Project or MyNewt to name a few.
