Hi BSTRobin, can read chip ID at the first time BHA260 power up like the picture below. then if there is no action the BHA260 chipset will go to sleep and I cannot read the chip ID again. That is my conclusion when I read the datasheet on page 37. Thanks   ... View more

Hi BSTRobin, Sorry for the late feedback. I found the reason. BHA260 auto goto sleep after power-up if no action and very quick: you can refer to datasheet page 37. My question: how to keep BHA260 chip set in the ACTV mode after power up? thanks ... View more

Hi  BSTRobin, sorry, I re-check my hardware setup the HSDO pin connected to the ground. Thanks for your code. I will re-check again my source code. ... View more

Hi BSTRobin, I checked HCSB pin connected to VDDIO_1V8 HSCX and HSDX connected to pull-up registers HSDO connected to VDDIO_1V8 (select the address 0x28) I tried with a command and I received ACK with the address 0x50 thanks ... View more

Hi BSTRobin, yes. At the first testing, I showed you above, I used address 0x28 << 1 = 0x50 then I received ACK from the BHA260 chipset. But I don't know why the chip ID that I read is 0x00. Currently, I trying to upload firmware to the BHA260 chipset to see how. ... View more
