We are using MC60 module, and want to show GNSS LED indicator (similar to NETLIGHT which shows GSM network status) to show the GNSS network connectivity status. How can we do it?
Thanks!

Hi Trakbond:
If you are using EVB+TE-A,There is an indicator light next to your GNSS antenna.
When the GNSS function is turned on, it will light up, and when the location is successful, it will blink.
@Winnie.Xi-Q
How can we control the GNSS antenna through OpenCPU program. We want to show a custom LED which will be ON when there is no signal and blink once every 3 seconds when in tracking mode.
The NMEA statement returned by GNSS can be used to determine whether the module has been located successfully.
"NMEA --> GGA -->Status’ the bits.If A is located successfully, V is not located successfully.
Thanks for clarifying got GNSS LED. We want to control the Network LED to show various states (Not connected to network, Connected to Network, PDP context active or inactive (GPRS), etc). But the LETLIGHT PIN (no 47) has limited function only.
How can we control Network LED?
All these can be controlled by judging the NMEA statement of the GNSS module. There is no direct knowledge pin on the GNSS module, so you need to control the GPIO after judging by yourself.
My last question was related to GSM status (not the GNSS), what is the command for getting GSM bits?
“We want to control the Network LED to show various states (Not connected to network, Connected to Network, PDP context active or inactive (GPRS), etc). But the LETLIGHT PIN (no 47) has limited function only.”
NET Network instructions in the module corresponding hardware development manual has the corresponding introduction, please refer to the hardware manual search “Network status” to learn.Thank you.
Sorry but
Network status is hardware design reference doc does not have any details about how to change the default behaviour.This state is the default and cannot be changed.Thank you.
Hi @Grey.Tu-Q
I want to lid a LED using MC60 GPIO PIN (say SD_CMD Pin no 7, using multiplexed function), but no sure what is the Voltage (max/min) and Current (max) characteristics for MC60 GPIO pins. Can you please confirm Voltage/Current ratings for GPIO?
Dear trakbond
The input and output voltage domains of all PIN pins are described in the module’s OPEN hardware design manual.
Take your PIN7(SD_CMD) pin for example: the input low level range is “0~0.25VDD_EXT" and the input high level range is "0.75VDD_EXT~VDD_EXT+0.2”.The maximum output low voltage is "0.15VDD_EXT “, and the minimum output high voltage is” 0.85VDD_EXT ".
