Hi,

I think you got your answers here.

Hy, i have bt840 module and segger but i dont know how programming module, can you give me some tips?

@Punit: I suggest that you open a new thread, and try to describe your issue in more detail. What SDK and Softdevice do you use. What example code, etc... There can be many reasons why it doesn't work. When non-BLE examples work, but BLE examples don't, and assuming that you have remembered to program the Softdevice, the usual suspect is wrong 32.768kHz oscillator settings.

Hello, i am facing the same problem as above.I am able to program the above module through Keil/NRfgO, but not able to detect the module on phone.@Sundeep, were u able to find the solution?

The nRF51-DK and nRF52-DK are now less then $40.00 USD from Nordic's franchised distributors . You can use these for development and also as a J-Link to program and Debug your own target board when ready...

A good option here. Full support for nRF51 & nRF52. Supported by all IDE including OpenOCD and Eclipse on all platform Windows, OSX & Linux

You can try nRF5x module and jtag from here.

You need some SWD (Serial Wire Deboug - 2-wire standard interface used by smaller ARM cores but compatible with JTAG) device for debugging and programming of nRF51&nRF52 chips (once you have some serial bootloader in the firmware - which could use UART for instance - then you can continue without it for FW upload but not for classical halt/step-by-step/run debugging). So FTDI or Arduino tools won't help you with that. There are more options for SWD debugging of ARM Cortex-M processors such as nRF51/52 but I'll list 3 most common:

LPC-Link originally meant for NXP LPC Xpresso product line - you can get as cheap as 15EUR (+ shipping?), e.g. see Embedded Artists shop here.
ST-LINK originally meant for STM8 and STM32 product lines - you can get it on various ST Micro development boards ("Discovery" being the cheapest options, starting at 7~10EUR + shipping), see various options such as this one at Mouser.
SEGGER J-Link universal programmers which come in various packages and licenses directly from SEGGER or in bundles with other development boards (either separate or "on-board"). You can get EDU version as low as 60EUR (+ shipping) but the best option today is grabbing nRF52 DK (or nRF51 if you want to use that particular chip variant for development) which starts at 40EUR (+ shipping) because it has SEGGER J-Link OB (which is then usable for SWD debugging/flashing of any compatible ARM Cortex-M) and you can directly prototype with the nRF5x chip on it (and switch to custom HW later).

Now first two options (LPC and ST Link) are theoretically usable with nRF5x but as there are no out-ot-the box support in Nordic and Segger tools for them you will need to look here at forum (at least for ST-LINK you should be able to find some cook books e.g this ST-Link + Keil uVision) and around internet how to make it work. However I like ST-LINK for STM32 and LPC-Link for NXP chips I would never recommend to save 30EUR and bother with anything else then SEGGER J-Link once developing on nRF5x chips. You might get that way once you are skilled with particular STM or NXP tool chain but then you aren't posting such questions to this forum...;)

Cheers Jan

Hi. If you dont want to buy nordic DK only the one resonable option for nice development capabilities is www.waveshare.com/nrf51822-eval-kit.html . But dont forget to have explicite debuger, personaly I am using stlink but i would recommend Segger for nrf.(going to make your life easier)

Totally agree with @endnode - with anything like this, it's always best to start with the manufacturer's own development/evaluation board. That way, you will get support direct "from the horse's mouth".

Once you have gained sufficient understanding & experience with the manufacturer's own kit, you will then be able to properly evaluate 3rd-party offerings such as seen on places like ebay.

Hello

I ordered the same board. I also ordered a Stlink v2 Link aliexpress

Make sure you search on google en install the stlink v2 driver. Then download keil en your ready to go. make sure to select in keil stlink v2 as programmer with the use of SWD. (make sure you flash the right softdevice for a 2nd reversion chip). Here are some instruction how to get going stackexchange

Hi. If you are starting with nRF5x development then simply purchase one of the DK boards (nRF51 or 52 depending on what chip you want to use in final product). You can test the FW easily with them (you will also learn how to upload the code with SEGGER/nRFgoStudio/nrfjprog tools - either from GUI or command line or though some IDE such as Keil or Eclipse or IAR) and once you know what to flash to your specific boar then simply use debug out ports P19 or P20 (there are tutorials in Blog zone as well as useful hints in this Question zone). When it comes to Arduino I doubt there is any SWD plug (because that's the only protocol you can use with nRF5x chips) which would know the parameters of nRF5x and works out of the box, but guys from Adafruit sell nRF51 based boards so they might have some tutorials for you. Cheers

Can somebody post all the parts that need to be purchased, with a board like this on ebay. Also what software to use? can I program with Arduino?

If all pass, try to change SOFTDEVICE_HANDLER_INIT see this thread. Btw, debug should be simply possible if you are using uVision. There is DEBUG menu.

@Vrabec - all steps pass, but no ble on control panel :-( how can i debug ?

RE: nrf51822 module

Vrabec — Wed, 11 Nov 2015 16:08:19 GMT

Hi, make ble_app_beacon working is quite simple when you have some experience with BLE :). 1st you have to upload softdevice with "flash_softdevice" to chip. 2nd you have to compile project. 3rd, you have to setup keil like in this thread and upload to chip. If all steps pass, you should be able see your BLE via nRF control panel.

RE: nrf51822 module

sundeep — Wed, 11 Nov 2015 10:58:38 GMT

@Vrabec - thank you. I have the J -Link programmer and am able to program the module. Tried many examples from the SDK , the Blinky one am able to get to work, however, non of the BLE ones (e.g Beacon etc) seem to be working. I uploading the ble_app_beacon using the "flash_softdevice" option. It uploaded just fine, says application started, however the device is not showing on the nRF control panel on my android. Same is the story with all other applications. Please advise

Regarding the IC Revision, using OpenOCD i can read the CONFIGID Register which have the HWID (Identification number for the HW), on my module that register value is 0xFFFF0072, then you go the Compability Matrix document and find out that this HWID corresponds to a third revision IC, Build code = Hx0, you can also find this information on the IC Chip Marking and the Product Anomaly Notice. You might find this post usefull.

@Carlos, thanks. I have order a J-LInk programmer, will try once it arrives.

Vrabec — Mon, 19 Oct 2015 12:36:40 GMT

@Sundeep: Arduino board or FTDI will not help you. You need programmer like J-Link (best support). Somehow it's also possible to make it working with other programmers, but this will require more time make it working.

RE: nrf51822 module

sundeep — Mon, 19 Oct 2015 11:49:55 GMT

Can these be programmed without a DK, say using an arduino board or an ftdi?

RE: nrf51822 module

Chris — Mon, 19 Oct 2015 07:48:16 GMT

I've ordered a couple of those; I believe they have no preloaded firmware, I plan to program mine using the Debug Out port of a nRF51 DK board.

I believe the module is a copy of this: www.waveshare.com/.../Core51822

RE: nrf51822 module

Vrabec — Mon, 19 Oct 2015 06:43:57 GMT

In addition, this product use 2nd revision chip. Therefore latest version of SD and SDK is not supported. See compatibility matrix. Regarding programmer, the easiest way is to use J-Link.

I have the similar understanding from all the eBay shops offering these very cheap modules with nRF51822. Btw. why you don't contact the seller or manufacturer? I've seen PIN allocation drawings on eBay as well so they should have some User Guide to these modules answering basic questions like yours...

RE: nrf51822 module

Carlos — Sun, 18 Oct 2015 19:41:33 GMT

I get the same module last week. In my case: 1.- It had no firmware preloaded. 2.- I use SWD for program it, using the ST-Link of a Discovery board. 3.- I think you have to program the bootloader and softdevice to the chip to be able to upload later the firmware OTA.
