Hello Felix,
Thank you very much for your assistance. After manually configuring the APN via AT commands, everything is working perfectly. The pass-through example with UART2: TX = 26, RX = 32 was very helpful.
Thanks again,

@felmue Hello Felix,
Thank you very much for your response. Do you have any sample working code for UiFlow with CATM?
The mentioned blue light blinks every 800ms, indicating no network connection. I tried the SIM card again on Mikrotik KNOT, and it works there. Hence, I assume that the SIM card is fine.
Maybe the Polish provider Orange doesn't automatically assign the APN. How can I configure the APN using AT commands?
Thank you.
Hi, I'm trying to run a project that can control a relay using LTE-M communication.
I'm working with the CATM (U128)
https://docs.m5stack.com/en/unit/cat_m
I'm using two different modules: Atom Lite and AtomS3 Lite, so in UiFlow v1 and UiFlow v2. While UiFlow1 has an additional CATM UNIT, UiFlow2 does not.
In M5Burner, I've set com.x to True and set the APN as required for my SIM card.
Does anyone have a ready-to-use project built with blocks using MQTT? Either for UiFlow 1 or 2. Because I can't get it to work.
While I've built a program on Wi-Fi that sends and receives MQTT, with the CATM I don't receive any IP as if it's not connecting to the internet.
On the module's page, there's only an example for Arduino and I'm looking for one for UiFlow.
Below, I've attached a screenshot of the blocks and while I can retrieve IMEI or CCID queries, I'm unable to connect to the internet.
The SIM card is tested on Mikrotik KNOT, where I also have LTE-M and I can send and receive MQTT there. The PIN is turned off.
I'd greatly appreciate any support on what and how I can check why I'm not getting an IP address. Thanks.
