Hello
I have the SparkFun LTE CAT M1/NB-IoT Shield - SARA-R4 with the Hologram card Item number: CEL-15087. When I attempt to use the Send or receive message sample I get nothing happening.
On the hologram site, I can see it is registered and I have a Device Number.
I register the Operator everything looks good;
13:59:44.425 → Connecting to option 3
13:59:47.943 → Network 310 410 registered
13:59:47.943 →
13:59:47.943 → Connection info:
13:59:48.011 → APN: hologram
13:59:48.011 → IP: 10.52.149.163
13:59:48.080 → Operator: 310410
13:59:48.080 → RSSI: 19
When I test the network:
14:01:32.993 → APN successfully set.
14:01:32.993 → Network set. Ready to go!
14:01:32.993 → RSSI: 99
14:01:33.063 → Network registration: Not registered
When I Send
14:02:54.159 → LTE Shield connected!
14:02:54.159 → Type a message. Send a Newline (\n) to send it…
14:02:59.137 → Sending: test
I have determined that the issue is with the Socket with I do occasionally get Socket 0 Connected. But even when that happens the data never seems to go. I added an external antenna, same issue.
If I try to reset it all by reregistering
14:28:04.668 → Connection info:
14:28:04.769 → APN: hologram
14:28:04.769 → IP: 10.52.149.163
14:28:04.804 → Operator: AT&T Hologram
14:28:04.838 → RSSI: 16
Then resend a message:
14:28:38.554 → LTE Shield connected!
14:28:38.554 → Type a message. Send a Newline (\n) to send it…
14:28:56.048 → Sending: test send
14:28:56.083 → Connecting to socket: 0
I hope someone can help, I am at my wit’s end. Additional info
MCU - Atmega 2650 - using software serial to LTE Shield pins 12,13 - Communication to the board is not an issue
Sorry for the long post, any help would be greatly appreciated.
