Hi, board has been build and checks done, code flashed to Arduino. BT module fitted while pressing button and light flashes 2s on 2s off, reset Arduino but light L continues to flash. Tried many times reinstalling BT but can't get past this point. Any suggestions?
Ah, I might need to clarify the documentation there. By blink continuously I mean it will keep blinking - as it is doing. The fact that the BT module LED starts blinking fast means that it's successfully configured.
The problem is the iPhone I'm afraid. Apple don't implement the full suite of bluetooth protocols - one of the ones they haven't got is the serial over bluetooth that the eChook uses. As a result it will appear to any non-Apple device!
It sounds like everything is actually working - I'll update the documentation with a caveat about BT and apple devices!
Got hold of an android phone and now up and running. I used the FREEBOARD dashboard which is attached to DWEET and this is a piece of cake for remote reading (as a clanky mech eng, i found the NODERED a bit confusing). I'm now on to the current sensor. Can you confirm which pins on the sensor connect to which pins on the plug please. I did have it running for a few minutes (reading a bit low) but now the current is showing 168 A on the APP and is not affected by my adjustments. I'm using a 30A power supply with current limiting. Any suggestions?
Awesome! I'll be honest I thought freeboard had stopped working as a free service, I've been using just the dweet.io/see interface.
Can't check the current pins immediately I'm afraid, I'll try do it tonight. With no current flowing there should be about 2.5v on both the sense and reference pins from the sensor. If you can see that on the input connector, then the problem is on the board, if not, it's on the sensor end. It sounds like you might have the sensor in short circuiting to 5v, or the sensor reference shorting to ground...
HI, Ive got it working now (loose bit of solder) although the APP is showing around 1A below my measurement across the full range of 0-17A. I guess I need to calibrate. The voltage is not showing up although I don't have the "lower battery" connection in place yet, not sure if that would affect it?
Did a calibration. Two meters reading 16.74 and 16.8 A on the supply and A2 pin reading .444V =37.16. Flashed Arduino and reading on APP still 16.0 A. Would sensor cable length and type make a difference?
