  @Pete-R Maybe try logging in to the helpdesk portal with a new/different email? If that still doesn't work, please post a screenshot of the error you're seeing.

  @Lazar-Demin thanks! So far we want to make hook up one or two BNC connector (with voltage divider/LLC) to GPIO pin(s) and maybe add a USB hub in-between the Omega SoC/LTE module to support more USB devices (from what I gathered the LTE is module is directly tied to the USB pins on the SoC).

  Agree with @crispyoz's recommendation to clean the contacts. If it were a hardware issue or manufacturing defect, it likely wouldn't have worked at all. I also recommend checking if the contacts have been damaged during SIM card insertion and removal.

  @jasoneer Try again using the very latest build (b253). It looks like the kernel checksum changed when we released b253: (screenshots from http://repo.onioniot.com/omega2/packages/core/ and http://repo.onioniot.com/omega2/images/) More info on openwrt kernel checksums here.

  Thanks @crispyoz I had ordered the ANT-LTE-RPC-UFL before I saw your message: https://www.digikey.com/en/products/detail/linx-technologies-inc/ANT-LTE-RPC-UFL/11314387 https://www.mouser.com/ProductDetail/Linx-Technologies/ANT-LTE-RPC-UFL?qs=xZ%2FP%2Ba9zWqZk6bOn%2FzoXVw%3D%3D They work well for WiFi/LTE/GNSS but you need 4 of them for completeness. Once I saw your message, I also ordered the ones you recommended which just arrived today: https://www.digikey.com/en/products/detail/pulselarsen-antennas/W6113B0100/7667502 https://www.mouser.com/ProductDetail/PulseLarsen-Antennas/W6113B0100?qs=pfd5qewlna7l9rNmj68a0g%3D%3D They work as well as the ones I used before except you have to cross the LTE and diversity wires over each other when the antenna front/label is facing you or twist the wires around so the connectors line up when the antenna back/label is facing you.

  Hello @teddylambert Ideal solution—Is it possible to accomplish the omega2-ctrl gpiomux set spi_cs1 gpio command in a C program? Yes, if you want to learn how, have a look at the omega2-ctrl sources on github, in particular gpiomux.c and gpiomux.h What it does is setting and clearing bits in the GPIO1_MODE and GPIO2_MODE registers of the MT7688 SoC (see MT7688 Datasheet page 61ff). These registers are at 0x10000060 and 0x10000064 in the physical address space - so to access these from user space (any regular program runs in user space), omega2-ctrl needs to map that part of physical addresses into user space. The gpiomux_mmap_open function in gpiomux.c maps 0x10000000..0x100003FF into the gpio_mmap_reg pointer, using the linux mmap function. After that, SoC registers can be accessed via that pointer (i.e. gpio_mmap_reg+0x60 points to GPIO1_MODE). Would a system() call work (something like system(omega2-ctrl gpiomux set spi_cs1 gpio))? Is that the best way to accomplish it? Yes, using system works too, and is much less code. So that might be the best way in your case However, I mentioned all of the above because via mmap you could access all SoC registers, and do many more things (superpower, be careful!) not exposed by omega2-ctrl. Another reason to directly access SoC registers and bypass all Linux tools would be speed - system() is orders of magnitude slower (several milliseconds) because it involves forking a shell which in turn forks omega2-ctrl. That's fine for a one-time setup operation, but sometimes one needs nanosecond order speed, which is what mmap-ed direct access to SoC registers can deliver.

  @nro The power supply voltage should be 5V (+/-5%) How do the power issues present? A good place to look would be making sure enough current is supplied - the cellular modem is especially power hungry. Btw the hardware design of this product is open source, schematics and more can be found at https://github.com/OnionIoT/Omega2-LTE

  @Tanner-Henhawke 4 Years later and it's still an issue. Had a "," in the passphase and ApCli would loop connect/disconnect. Your discovered resolution is still valid.

  Ethernet port 2 (PHY2)

  Hi @vrinda-nair-0 the MT7688AN SoC (see Datasheet) has 5 Ethernet Ports, numbered 0..4. Those 5 ports are part of an internal switch (as the MT7688 is an internet router chip), that switch has two more (internal) ports 5 and 6. As far as I understand, the internal port 6 is the actual eth0 interface, and the standard switch config is such that port6 and port0..4 work as a simple switch. The internal port5 could be configured as an eth1 interface, and switch config can be modified to connect some of the external port0..4 to eth1 rather than eth0. There is (at least in vanilla OpenWrt builds) a utility called swconfig that can be used to view and modify switch settings. But all of this hinges on one not so well documented detail: bits 16..20 in the AGPIO_CFG (0x1000003c) register. Bit 16 must be set to 0 to enable ethernet port 0, and Bits17..20 must all be set to 0 to enable port1..4 (unfortunately, altough there are 4 bits, ports1..4 can only be enabled or disabled together). See MT7688 datasheet pg. 59ff. By default, the AGPIO_CFG is set to 0x00FE01FF, which means port0 is enabled (bit16==0), but ports1..4 are disabled. If you have the devmem utility (not sure if it is part of the standard Onion FW, but it is available in OpenWrt), you can view the current AGPIO_CFG: devmem 0x1000003C 32 And to make ethernet ports1..4 active (and in turn loose GPIO14..29): devmem 0x1000003C 32 0x000001FF Hope this helps!

  I also followed the guidance on this thread, and successfully created a mosquitto client in our pre-existing C++ application. Thank you very much for both the questions and the answers. I cannot express how useful this thread has been to me. Very unlikely I would have ever succeeded on my own.

  Posting the output of "ip a", "ip r" and, very specially, "brctl show" would be very useful to help diagnose the situation and see if you have a router or a bridge.

  Hi @crispyoz, Sorry for the late reply, i have been trying to roll-back to the version where i observed this problem, but that seems a bit harder than i thought. We've been testing with travelmate as a plugin these last couple of days, but if you say you haven't experienced the problem i described it gives me hope again to solve this without extra plugins... I'll try to get back to you as soon as i achieve breaking it again... bye tony

  @amanda Este foro es para soporte de dispositivos Onion Omega2, no para productos Arduino. ¿Está utilizando un dispositivo Omega2? Si es así, describa su configuración.
