My Moto G running 4.4.4 has picked up other devices with BLE scans, so I don't think it's a problem with my phone. I think I'll order a CC2540 BLE dongle and run the TI BLE sniffer to try to figure out what's going on.Ralph Doncasterhttps://www.blogger.com/profile/00037504544742962130noreply@blogger.comtag:blogger.com,1999:blog-6245413346375218188.post-24969169499129913042015-04-24T13:59:05.143-07:002015-04-24T13:59:05.143-07:00followup: I got the ble transmit working with 2 ot...followup: I got the ble transmit working with 2 other modules I received, not sure what I did to the first ones, look real (baite).

In my tests, it turned out to be much more accurate when checked on the TX node after getting back an ACK from the RX, instead of using it on the RX node like the docs mention.

I've tried it, plus some of the spinoff libraries, but no luck seeing the NRF24 on my android 4.4 phone. Trying to figure out if it's my setup and code, or some limitation in Android.protovisionhttps://www.blogger.com/profile/02183122012381759005noreply@blogger.comtag:blogger.com,1999:blog-6245413346375218188.post-90285175427429552262015-02-19T16:00:52.871-08:002015-02-19T16:00:52.871-08:00I've got enough to part with a few, and they&#...I've got enough to part with a few, and they're small enough I could probably send them cheaply in a first class envelope.

For my purposes, the 32byte tx size might work out ok (just need rssi of beacon), but I am curious about one of the arduino libs having a receive function for the nrf24l01, I think it can only see other (similar) broadcasts.<br /><br />I was just looking at the SE8R01 as well, any chance of buying some of your spare parts? (se8r01, attiny88-au + breakout boards, etc). I'm in Toronto.<br /><br />thx, ttyl<br /><br /> <br /><br />protovisionhttps://www.blogger.com/profile/02183122012381759005noreply@blogger.comtag:blogger.com,1999:blog-6245413346375218188.post-72652425338519673282015-02-14T12:46:59.324-08:002015-02-14T12:46:59.324-08:00I mentioned how I wired up the t88 to the nrf modu...I mentioned how I wired up the t88 to the nrf module, so I'm not sure what else there is to write about the $1.50 nodes I made. I've been looking at the ble beacon stuff too. I'm hoping to find nrf compatible modules that can transmit >32 bytes for full BLE compatibility. The SE8R01 turned out to be limited to 32 bytes like the nordic chip. Next I'll try a BK2423-based chip.Ralph Doncasterhttps://www.blogger.com/profile/00037504544742962130noreply@blogger.comtag:blogger.com,1999:blog-6245413346375218188.post-26749600716937854242015-02-13T09:15:18.019-08:002015-02-13T09:15:18.019-08:00thanks for reply, I noticed it didn't have the...thanks for reply, I noticed it didn't have the USI or SPI, but I wasn't sure if the technique you have needed either of those at a low level. As it turns out, I'm short a few GPIO, so I'm changing to an t44a or t88a.<br /><br />Also, any chance of a small writeup about your $1.50 nodes?
