What is the maximum value of HS_STARTUP_TIME for BlueNRG-1?
Hi friend,I want to extend the HS_STARTUP_TIME for BlueNRG-1. What is the maximum value of HS_STARTUP_TIME for BlueNRG-1? I saw the datasheet AN4494 it says that "XTAL_startup = XTAL_startup_measured*1.2*1.1*1.3 = 1.716*XTAL_startup_measured". So 19...
aci_gap_set_non_discoverable intermittently returns `COMMAND_DISALLOWED`
I am using the STM32WB5MMG. Once per minute the chip wakes up and performs a measurement, then connects to another device to transfer the data. After transfer is complete, the chip disconnects (using aci_gap_terminate) then waits for 100 ms, then sto...
