Programming ble_app_hrs via DFU on S310V2.2 Doesn't Work But Programming Blinky via DFU Does Work

[michaelbester101]

I have successfully gotten the DFU to work on the NRF51422 S310V2.2 softdevice. I can download blinky app via the nRF Toolbox DFU application and all works great, but when I download a modified version of ble_app_hrs to the PCA10003 board, it doesn't run correclty. I can't get a device to show up when I search BLE on the nRF Toolbox HRM app. I have relocated the code in the ble_app_hrs project to IROM1: 0x1D000 and IRAM1: 0x20002400 (same as I did for the blinky code). Is there something extra I must do to get the BLE to work when jump from the bootloader to the app?

OK. I had to completely power cycle my Iphone for the Nordic Toolbox to receive heart rate data. I wasted the day thinking it was a firmware or SD issue, when in fact it appears to be a Nordic Toolbox app issue (I'm using IOS8.1). Hope this can save some time for other people having similar issues.

I am happy about that you are making progress. I remember I had similar issue on my IPhone perhaps couple of times, it did not work until I restarted the phone, but that was with IOS 6 or IOS 7. Feel free to add any followup questions related to your original question. If you have an unrelated question, please create a new thread.
