https://devzone.nordicsemi.com/f/nordic-q-a/19961/s332-softdevice-not-working-with-ble-examples-of-sdk-12-1-0Hi, I am new to nrf52 series and I have just started playing with NRF52 series Development kit. I am working on a project that requires the functionality of both ANT and BLE. The hardware I am using is NRF52 series nrf52832 development kit with a PCA10040en-USTelligent Community 13Fri, 24 Feb 2017 12:37:26 GMThttps://devzone.nordicsemi.com/thread/77674?ContentTypeID=1Fri, 24 Feb 2017 12:37:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bd1cfafb-d361-41d7-8e32-2caba5e3297dPetter Myhre<p>It would work, as long as the address is 0x1E30 or higher, but if the address is too low sd_ble_enable() inside softdevice_enable() will return an error, and the required ram address would be in app_ram_base.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/77672?ContentTypeID=1Fri, 24 Feb 2017 12:30:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fadce201-06c0-4fc2-8983-d8a076dd8e86FormerMember<p>I have understood that a valid ram start address and ram size is very critical and it can be obtained by calling the softdevice_enable() function. But this ram start address is required before the execution of the program and I would at least need to run the program once correctly to call the softdevice_enable() function. How can I call the softdevice_enable() function with a wrong ram1 address? would it work then?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/77671?ContentTypeID=1Fri, 24 Feb 2017 12:11:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:251e8a5a-f7b5-41ec-af0a-1ddb4903833aPetter Myhre<p>It is the application ram starting address required by the SoftDevice. There are some more information in SoftDevice RAM usage in the S132_nrf52_3.0.0 migration document and the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.sds/dita/softdevices/s130/mem_usage/mem_resource_map_usage.html?cp=2_3_0_0_13_0">memory resource map and usage</a> section in the SoftDevice specification.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/77673?ContentTypeID=1Fri, 24 Feb 2017 11:54:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ee68c0c1-ecd6-4dd2-830f-e6495f4c41c1FormerMember<p>can you please explain what is app_ram_base in softdevice_enable()?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/77670?ContentTypeID=1Fri, 24 Feb 2017 11:21:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:86b04b80-6733-4f28-9f7b-c0b581ed5381Petter Myhre<p>Have you adjusted the ram start and ram size according to app_ram_base in softdevice_enable()? I get IRAM1 Start 0x20002560 and Size 0xDAA0.</p><div style="clear:both;"></div>
