0xDEADBEEF, 722, src \ ll_adv.c

Question

Hi all, 
 I use nRF51822, sdk_v5_0_0_34603 and s110_nrf51822_6.0.0-5.beta.
In a different periods of time appears error "0xDEADBEEF, 722, src \ ll_adv.c".
Error appears only with battery powered device (tested with different batteries).
What may be the reason for this error. 
 Best regards,
Peter

Hi Peter, 
 The issue you see is due to a slight incompatibility between your HW revision and the s110 6.0.0 SoftDevice. As you can see from the S110 release notes and the nRF51822 compatibility matrix in the nRF51822 migration document (nWP-018), this SoftDevice version is not production level tested on older revisions of the nRF51822. 
 A workaround that enables you to do development wit S110 6.0.0 on older hardware, is to implement the fix for PAN ID 11 (see nRF51822-PAN) while advertising. In short, this is setting the power mode to NRF_POWER_MODE_CONSTLAT, see the nRF51 Series Reference Manual (nRF51 RM). The drawback is a slightly higher power consumption while the power mode is set to NRF_POWER_MODE_CONSTLAT. 
 On newer revision hardware (see the compability matrix), no workaround is necessary. 
 All the documents mentioned can be found in the "Downloads" section of the nRF51822 product page on nordicsemi.com: www.nordicsemi.com/.../nRF51822
