Re: waiting for an interrupt flag to be set
Is there any difference / benefit to using a time.sleep in a tight loop rather than a pass ?
Code: Select all
while x = False:
pass
while x = False:
time.sleep_ms(10)

BLE - Reading the connected device RSSI
Hi;
Yes, lots of questions about BLE, sorry about that.
While I can connect to the device and read it's service values, there's no service address for the RSSI.
So how can I get a connected device's RSSI value ??

Re: waiting for an interrupt flag to be set
Jimmo, I can work around this by setting a error flag and if the flag is set and connection fails, then clear the flag and retry the connection. This prevents the connection failure but wastes time attempting the connection twice, and it only appears to happen on the first connection after the error...

Re: waiting for an interrupt flag to be set
I need for this to be bullet proof as it will be running un-manned. I am getting a lot of disconnect interrupts with handle 65535 and this then appears to kill the next connection. This loop is simply stress testing, and I get the 65535 handle VERY frequently ! h1 = j.Dev(b"\xcb\xd0\xc5\x0c'\xbd") i...

Re: BLE Broadcasts vs Scans
Also, not sure if this is related to the gap-scan timing you mentioned, but very often devices which the mac is known and can be connected to do not appear in the scan results, whether or not they are already connected. Only if I scan several times for a minute at a time will these devices be eventu...

Re: BLE Broadcasts vs Scans
Jimmo, thanks, that's very helpful.
I have already checked the scan manufacturer's data and it does not contain active data, only static data such as the mac address and a couple of other byte variables.

BLE Broadcasts vs Scans
Sorrie for all of the BLE questions, I have googled but are not able to find a direct answer. It appears that beacons broadcast and that it is not necessary to connect to the device, but just to listen for a specific device broadcast and read it's data. But how would you do this ? - I know that with...
