Having recently received a small development grant I need a number of devices for a tele-health application.
B542 has been showing an expected delivery time of 56 weeks for many months now - what is the current status/expectation
Alternatively I can deliver 15 prototypes using Boron 2G/3G but the 3G network is closing down (hence a waste of resources for a tight budget but may be only near term option). Telstra 850 MHz closes in June 2024, Optus and Vodafone both use 900MHz and have not announced shutdown dates. All three Australian carriers have already shutdown 3G on 2100 MHz.
Does Boron 2G/3G work with all 3 Australian carriers in the 850/900 MHz bands?
Will it switch to another carrier when Telstra shuts down in June 2024
Boron 2G/3G is shown as available but in what numbers?
The B524 is on allocation, which in this case it means that they’re being made in limited quantities due to supply chain constraints, but all of the units that are being made have been allocated to enterprise customers who have contracts for a guaranteed number of devices. Once the supply increases and there are extras, they will be available in the retail and wholesale stores again.
The BRN314 (2G/3G with EtherSIM) works with Telstra (3G B5 850 MHz), Vodafone (3G B8 900 MHz), and Optus (3G B8 900 MHz).
The BRN310 (not EtherSIM) only works on Vodafone and Optus.
All models automatically switch to any available carrier that is supported by the SIM.
The BRN314KIT is limited to 5 unit purchases and only in kit (with breadboard and accessories) in the retail and wholesale stores.
The BRN314TRAY50 (tray of 50, bare) is on allocation.
Thanks @rickkas7 for the prompt and precise answer.
While I understand the current position it puts me between a rock and a hard place. We have just been awarded a small R&D grant that requires the build of 15 prototype units. I was planning on using B524’s but had to think about the 3G option, wasteful as it is, given the long order times for the B542’s. It now appears that the 3G option is also not achievable.
I may need to consider using a mix of Argons and 3G Boron’s but that is a pain given the need for patients to enter their SSID and password - something that cannot be assumed for many of the intended clients/patients. My aim is to have a unit that can upload data on a daily basis with no user intervention.
While I have your attention - I am currently using your DMA code to sample data at a relatively low rate (200-300 Hz). I note your caveat that the DMA code is not supported and may break in the future. Am I taking a dangerous path in using that code?
Again, thanks for your prompt and concise response.
