Re: HC-06 Bluetooth Serial Module (HCARDU0004 & HCARDU0064)

I would need to connect the slave module to a short length of cable terminated in a USB C plug so I cold plug it in to the pedal's USB connector. I’m not sure if I’ve misunderstood this bit but you won’t be able to connect the slave module directly to the existing USB port on the pedal. Your best o...

Re: mLink 20x4 LCD display with Raspberry Pi - Cursor position not working

It's ok, I didn't spot it straight away. TBH, I'm surprised it didn't throw a syntax error.

Re: mLink 20x4 LCD display with Raspberry Pi - Cursor position not working

Any ideas what is wrong?

Yes, the issue is caused by the equals sign (=) in your code. You should change this line:

  1.  ml.cLCD_Cursor = (0x56, 3, 3)
...to:
  1.  ml.cLCD_Cursor(0x56, 3, 3)

Re: mLink 1ch (HCMODU00182), 2ch (HCMODU0183), And 4ch (HCMODU0184) I2C / Parallel Relay Modules

Hi Chris, I've been looking at the example sketches for the relay modules. The Read_Relay_0.ino has an error. The I2C address is defined as I2C_ADD. When this is used in the sketch it is add. Thanks, that error has been there since 2021! The example sketch Set_Relay_On_Time.ino isn't updated to incl...

Re: LongReach (LoRa) mLink Module (HCMODU0250)

One further thing, I think that the LongReach transmit example should have the line while(mLink.LORA_Tx_Busy(I2C_ADD)); after each transmit. Without it I don't always get the transmission, Good point. Technically because the examples invoke a delay after transmitting it doesn't need that line but I...

Re: LongReach (LoRa) mLink Module (HCMODU0250)

Thank you. I had missed the tabs on the examples and only seen the first one. I suggest retaining LORA_Tx_Done with the correct meaning as deleting it would break user code. Easily done. Just for reference, I've now updated the Arduino library and python module. The LORA_Tx_Done() function is now d...

Re: mLink 1ch (HCMODU00182), 2ch (HCMODU0183), And 4ch (HCMODU0184) I2C / Parallel Relay Modules

Yes this worked a treat! So the next question is: how can I prevent the relay going into timer mode? Could I permanently link the clear pads, or use a resistor/capacitor combination. You could permanently link the clear pads. This would cause the module to reset to default every time it is powered ...

Re: LongReach (LoRa) mLink Module (HCMODU0250)

They're in the first post of this thread under the raspberry pi section of the post. If you using LongReach mode then you can use the 'mLink LongReach receive example' to monitor the transmissions from your Arduinos.

Re: LongReach (LoRa) mLink Module (HCMODU0250)

Hi John, I am having a lot of difficulty getting these to work. I have had some success sending from the RPi 4 and none at all from one Arduino to the other. Is there any way to check whether an mLink LoRa is working? If it’s convenient to do, the easiest way to test them is to run the mLink_LongRea...
