MDBT-42V with nRF52DK

[Sudarshan J]

We are using an MDBT42V(29 pin) module which we discovered from the datasheet, comes with an nRF52832 controller. We are using a nRF52 DK to dump codes into this target board. But have so far been unsuccessful. Wanted to know if this is possible or if there's something else we should be doing.

Hello,

I saw the documentation for the MDBT42V here. In section 8 you can see the pinout. In the upper right corner is the J-Link module, which has the same layout as the nRF5x DK. Make sure to use the "Debug Out"/P22 pins.

I attached the PCA10040 schematics, which you can also find here (nRF52-DK-HW near the bottom of the page)

I don't know if you have tried this, but if you have, and you don't get the examples to work, do you have an Low Frequency crystal on the PCB (The X2 in the schematics for the MTBT42V in section 8)? Or do you use the RC Oscillator? To check whether this is the problem, try one of the examples that does not use the softdevice, such as the SDK\examples\peripheral\blinky example.

 

Best regards,

Edvin

Thanks for the response, Sir. We were successful in dumping the blinky example and other codes which did not use a softdevice, into our target board. We are currently having issues with BLE codes. Our schematics has the X2 (32Khz) crystal. We are able to communicate with the nRF Development board, but our target board isn't responding to BLE. What may be a possible solution to this?
