You're welcome. For the BL651 module, I see that it's based on the nRF52810 which is one of the 3 SOCs that the nRF52 Dk supports the development for. This SOC is referenced to as the PCA10040e, which is the Emulated version of the nRF52832 (the nRF52 Dk's on-board SOC). The issue here is that not all the examples on the nRF5 SDK support this SOC, So in this case (depending on if it supports the example features) build its PCA10040e folder. In the Blinky example, you have that folder. So you can easily build the example project and run it on this SOC. For using the nRF52840 dev kit to program the module, yes you can. Also with any nRF5 development kit. This is due to that all the nRF5 development kits have an on-board J-LInk chip, that makes the on-board SOC programmable just with a USB cable. Other wise you would need a Jlink debugger device to program the SOC. Same as with your module ! www.adafruit.com/product/2209 But, the good thing about the nRF5 dev kits is that the on-board Jlink debugger chip can also program external SOCs. So if you have an nRF5 based dev kit, you can just use it to do so instead of buying a standalone Jlink debugging device. In an nRF5 dev kit, you'll have the SWDIO, SWDCLK, VDD and GND pins exposed. And that's pretty much what you'll need. Once the on-board Jlink detects the external SOC, it'll disconnect from the on-board SOC. And so any SOC related communications will be performed on the external SOC, including flashing an application. devzone.nordicsemi.com/f/nordic-q-a/14058/external-programming-using-nrf52-dk nRF5 dev kits also have a connector for that, in case your external module has an SWD connector on it. So you can easily connect it to the dev kit using an SWD cable. www.adafruit.com/product/1675 The connector is named (Debug out), and it's on the right of the programming USB port. Example of a dev board that has the SWD connector, and uses an nRF52840 SOC based module (Raytac MDBT50Q). www.adafruit.com/product/4062 Hope that helps, I have this board on my desk, so I might do a tutorial about that soon.

@@nrf5dev Thank you so much!!!

Glad you found it helpful! For your question : It's the same as on your mobile, you also need an application on your laptop. If you're on Windows 10 try this one : www.microsoft.com/en-us/p/bluetooth-le-lab/9n6jd37gwzc8 Note : You'll find your device on your mobile and laptop's Bluetooth settings, if it is advertising some specific services, like the keyboard hids BLE service, or the mouse hids BLE service ... Hope that helps,

Hello, It's not an emulator, it's just a tool that let you control your Android phone from PC. So you'll need to attach your Android phone via USB. Tool source : github.com/Genymobile/scrcpy

@@nrf5dev Thanks. I was thinking of an emulator which supports bluetooth. For folks who don't have an android phone at hand.

try segger v 5.66

thanks bro @@nrf5dev
