Calvin, You cam buy a Nordic Development kit for about $50 dollars or less. It has the J-Link OB device on it for swd programming and debugging.

Best solution imho, never had a problem with it programming the nrf5 modules, just drag & drop from Windows file explorer.

I agree with Jokgi, but nonetheless for anyone interested in the Black Magic Probe alternative, here's an article on how to make a BMP from a $2 Blue Pill board:

i use $10 replica Jlink from aliexpress works ok with the latest firmware without an issue. i use it just to flash bootloaders to cortex m0-m4 and nrf52's but it should work for any task that a genuine jlink can do.

Jon Raymond

There also is an "Education" version of the Jlink for $20 if you want an official one with access to nRF Command Line Tools.

Jokgi

@Jon-Raymond Correct. It is a nice product for the price and the intended user. As Jon mentioned, you can use the command line tools as well as nRFconnect and also has direct hooks into the Segger Embedded Studio which is a fully functional IDE / compiler/ Debugger and is free when used with Nordic Semi devices.
Plus there is no license conflict as there is when using one of these cheap overseas j-link knock offs. (Which could "break / brick" anytime doing a "official" Segger update on these clones.)

@orhanyor good to hear! i ordered that as well since just to try it out in hope that it would work. now that you've said that, maybe i shouldn't worry too much then.

orhanyor

@Calvin-Khung Well im actually surprised that it still works because people are reporting they might stop working after a firmware update so you might wanna hold back on that other than that it works surprisingly well. i bought another as my back up plan which im expecting it in these days. its abit different than the one i have. this one is much cheaper and looks like jlink edu mini rather than a normal j link with a black box.. i ll see if it works when i receive it, here it is.

i just received this little thing, tested it with atmel studio just to flash some M4 boards and it worked nicely. i wanted to update its firmware via jlink(playing with fire) but it didnt let me saying its up to date so its all ok i guess. it only has 4 pins 3v, gnd, swdio, swclk. for $2.50 in total with shipping its a steal :)

Jon Raymond

@orhanyor Is it just me or does that micro usb connector look like it should be mounted upside down so it actually nests into the cutout in the board below it? Of course the pinout would be mirrored but it seems like a layout issue that they just ran with.

orhanyor

usb connector is actually nested as far as i can see but it dips 1-2 mm only. weird but it works so its all good :)

Does anyone have any experience with the minew modules?

I've been using the Fanstel BT832 series with success, but I have been looking at this one to get a few more hand-solderable GPIOs.

I received a few of the Minew MS50SFB modules. They appear to need unlocking similar to the E73 modules. I have tried using instructions as for E73, but no luck so far with either

@nagelc If you do manage to get it working, I'd be curious as to what kind of range you get out of it a compared to other modules. The antenna pattern looks a bit different.

NeverDie

@nagelc It's a shot in the dark, but maybe you want to check the schematic for any differences with other modules that you've previously programmed successfully. Either it's a dud, or it must be that.

Did you try with nRFgo Studio ? I use that with NRF52 DK and it's simple. But I've not tried those modules though.

Jokgi

@Nca78 nRFgo Studio has been put to sleep. nRFgo studio does not have support for the newer Nordic devices. nRFconnect for Desktop has taken its place. I suggest when using the nRF52-DK (or any nRF52 based DK) that this newer utility be used.

Thank you I updated !

Jokgi

@Nca78 I suggest downloading the "command line tools" as well.
