3. Modify custom_config_qspi.h to use the RCX for the low power clock:
#define dg_configUSE_LP_CLK LP_CLK_RCX
4. Build the DA14681-01-Release_QSPI target.
5. Run the program on a DA14681 pro development kit.
The program will trigger the BLE_MAX_DELAYS_ALLOWED assert in rwble.c within 10 to 20 seconds.
What can we do to both wake the system every 40 milliseconds and utilize the LP_CLK_RCX setting? Would you recommend we increase the number of allowed BLE delays, perhaps setting BLE_MAX_DELAYS_ALLOWED to 10 or more?
Thanks!
