I am new to Espruino and would like to try it for programming my RAK Wireless RAK8211-NB board (Quectel BG96).
In the official RAK wireless docs it suggests flashing espruino using nRFgo studio. The problem is that when I tried to get nRFgo studio from Nordic's site using this link , it sais that the application is Windows only, and I am using a Mac computer.
Is there any other way of flashing Espruino software into this board?
I don't have access to any Windows PC or virtual machine ATM and I also wonder if it willl work using a Windows VM in Mac OS.
I have found the app rknrfgo (MAC os version of nRFgo) on https://devzone.nordicsemi.com/b/blog/posts/tools-for-os-x-development and installed it on my MAC. However, I do not understand correctly how to flash the device, as the GUI is different thant the nRFgo studio one. I have attached a screenshot.
Should I just select the "Use code" checkbox, browse the location of the espruino hex file and then press Wipe and Program?
I have made it work.
These are the steps to do it here for future reference:
Great! Thanks for letting us know!
If you're using an nRF52DK to program the board it should also appear as a flash drive called JLINK - just copy your hex files there and you're sorted, no need for nRFGo!
I use a nRF52dk and it works fine from my mac as Gordon describes. I build Espruino and do everything on a macbook pro.
Note: the 8211 uses a BC95 cell module and a L70 GPS.
The 8212 uses the BG96. The BG96 GNSS has GPS and Glonass, so it has better performance.
You probably want to update the BC95 firmware at some stage. I just did mine today. It requires a bit of jiggery-pokery to do. You need to solder some jumper wires from two resistors on the board to the uart pins. You can then use the usb->serial board to download new firmware - you need Windows for this as the Quectel app is windows only. It works well running a Win7 VM using Virtualbox.
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
