[BlueNRG-MS] SPBTLE-RF maximum power output compared to BlueNRG-M0A
Hi,I am using a SPBTLE-RF chip and will switch to the BlueNRG-M0A soon. I am willing to estimated how much I will benefit in term of signal strength using this new chip.SPBTLE-RF chip is advertised (on website) to have a maximum +4dBm TX power output...
Resolved! STUSB4500 PD Controller -- unable to sink 20V/12V
Hi, I am working on a USB PD project. STUSB4500 is used to request the 20V/12V 3A from the source. I flashed the NVM inside of the IC. The writing on the NVM seems to be successful as I can read it back and verifiy it. After reconnecting it, I can re...
How to correctly stop scanning for beacons (entering low current sleep mode again)?
I'm using the BlueNRG-2 with FreeRTOS in Atollic TrueSTUDIO.I succeeded in scanning for beacons using:ret = aci_gap_start_observation_proc(160, 160, 0x00, 0x00, 0x00, 0x00);But after some time I would like to stop scanning and e.g. enter sleep mode a...
