as I have written in another post that I am trying to measure the current consumption of the mangOH red as a gateway between Bluetooth and LTE. For this I have followed the tutorial and try to get the mangOH Red to use its LTE transmitter. My success was mixed.
I am stationed in Switzerland therefore I am using the WP7502 and the SIM card which was supplied with the mangOH Red. There is some connectivity:
root@swi-mdm9x15:~# cm sim info Type: EXTERNAL_SLOT_1 ICCID: 89332401000004678476 Home Network Operator: Orange F IMSI: 208011500411353 Phone Number: root@swi-mdm9x15:~# cm radio Power: ON Current Network Operator: Salt RAT: LTE network (LE_MRC_RAT_LTE) Status: Not registered but currently searching for a new operator (LE_MRC_REG_SEARCHING) Signal: Strong signal strength (4) PS: Packet Switched Not registered (LE_MRC_REG_NONE)
But the network won’t let me connect and I don’t get my data into the cloud with the redSensorToCloud app.
- Does the supplied SIM card not work in Switzerland?
- When is the current draw of the mangOH Red the highest?
- Do the main current spikes already occur during the initial connection phase or would I have to be connected to the mobile network already to judge the maximum current consumption?
