Murata LBCA2HNZYZ-711 BLE module w/antenna priced at US$ 5.57 in Quantities of 1,000.
This includes FCC certification. This means for commercial sales, i don’t have to get the system certified. Certification is a large cost for radios developed to go to market.
Bluetooth Low Energy (BLE) has an approximate max data throughput of 10.6 KB/s. This is very constraining for large devices such as routers and smart phones.
For estimation I will calculate the time to upload to a 1 GB router.
1,000,000 KB = 1GB
1,000,000 /10.6 = number of seconds to upload
94,339 seconds to upload 1 GB
94339/3600 = 26 Hours to upload (Not very feasible for very large devices)
This might require a change on design specs, however very few devices need a 1GB upload.
Most Devices are under 1 MB. which would take approximately 95 Seconds. This is not horrible when trying to rescue a brick but very frustrating for production work.
Bluetooth Low energy is not in every smart phone, but is becoming common.
This choice has some positives and Negatives. It is not ruled out yet.
