nRF51822 in Taiyo Yuden module - anything special I need to do?

I have the nRF51822-DK and have been able to build and run the sample projects, e.g, ble_app_beacon.

I've just built a board using Taiyo Yuden's EYSFCNZXX module that's based on the nRF51822:

www.yuden.co.jp/.../TY_BLE_EYSFCNZXX_Overview_V1.0_20131225.pdf

I can download and verify the S110 soft device to the module (7.1.0), and download and verify ble_app_beacon, I can debug, the Kiel environment indicates that the app is running, but I don't see the module when I do a scan with my Android phone.

Is there anything that I should change in my settings when moving from the DK to the EYSFCNZXX module? Or is my hardware likely bad?

If it's of interest, the module is drawing about 0.85 mA when running ble_app_beacon. I only draw a quarter of that when running on the DK. My own board is just a breakout board, with the module, reset button (150 ohm to ground on SWDIO), and filter/bulk caps.

Thanks in advance!

  • I found the issue thanks to a pointer from another devzone user. The EYSFCNZXX has a 32MHz clock rather than the 16MHz that' standard for the nRF5822, and code needs to be updated slightly to accommodate this - in vesion 1.32 of the EYSFCNZXX Data Report document, the specifics are on page 21 (the last page).
